mhxandClaude Opus 4.8 0344e82223 🐛 fix(cache): avoid nil-pointer panic on empty redis read
redisCache.get fell through to `switch err.Error()` when Get returned a
nil error with an empty value, panicking on the nil error. simpleredis
never returns that combination today (a miss yields RedisMiss), so it
was unreachable in practice — but the read path is safer treating an
empty, error-free read as a cache miss, which also guarantees err is
non-nil before err.Error() is called.

mhxandClaude Opus 4.8 73e53c7d69 📝 docs: note replicas don't fall back to primary on outage
When RedisCacheReadHosts is set, reads are not retried against the
primary if the replicas are unreachable. Document that this, combined
with the default RedisCacheUnreachableBlock=true, means a replica outage
can block traffic while the primary is healthy.

mhxandClaude Opus 4.8 96beb9192e test(e2e/redis): exercise read-from-replica path
The redis scenario only set redisCacheHost, so it validated the writer
but never the round-robin reader path this feature adds. Split the mock
into two roles: the primary (--redis-addr) now answers every GET with a
miss, while the replica (--redis-read-addr) serves the hardcoded
verdicts. The scenario points redisCacheReadHosts at the replica (twice,
to drive round-robin), so the banned-IP-blocked assertion only passes if
the plugin actually reads decisions from the replica rather than the
primary.

The mock returns "f" (not banned) for 1.2.3.4 and "t" (banned) for
1.2.3.5, and the run.sh assertions match that. Both doc comments
described the opposite mapping; correct them to match the code.

31874263f2 🐛 Do not consider body unreadable when it's http.NoBody (#352)
* Do not consider body unreadable when it's http.NoBody

Fix #351

* 🐛 appsec: only drop unreadable bodies for methods that carry one

Gate the crowdsecAppsecUnreadableBodyBlock drop on the request method,
mirroring the reference lua-cs-bouncer METHODS_WITH_BODY list
(POST/PUT/PATCH/DELETE). Browser GETs over HTTP/3 never carry a
Content-Length (quic-go always wraps the stream in a non-nil body with
ContentLength -1), so they were all wrongly dropped; they are now
forwarded to appsec headers-only, while gRPC streams (always POST) stay
droppable.

mathieuHaandClaude Fable 5 be13c49144 🐛 ci(renovate): fix OOM crash and stop using Mend's default gitAuthor (#347)
The 2026-07-03 runs surfaced two config problems:

- The grouped "renovate/all" branch made Renovate fetch and hold the
  changelog of every upgrade instance separately (Traefik v3.0.0->v3.7.6
  was fetched ~10x, once per compose file), which blew the default 4GB
  V8 heap: "FATAL ERROR: ... JavaScript heap out of memory" (exit 134),
  killing the run after the branch was pushed but before the PR was
  opened. Disable changelog fetching (release notes were truncated in
  the grouped PR body anyway) and raise the Node heap to 8GB as a
  safety net.

- No gitAuthor was set, so commits were authored as Mend's
  renovate@whitesourcesoftware.com, which GitHub flags "Unverified"
  (Vigilant Mode) and Renovate warns about on every run. Use the token
  owner's noreply address instead.

26ce12f7e3 🤖 chore: adopt Renovate for automated dependency updates (#330)
* ⬆️ bump example image versions to latest stable

Align every docker-compose and Helm-values example on the same set:
- Traefik       v3.0.0 / v3.5.0 → v3.7.1
- Crowdsec      v1.6.1-2 / v1.6.8 / latest → v1.7.8
- Plugin pin    v1.3.0 / v1.4.5 / v1.5.0 → v1.6.0

No env / volume changes needed: every Crowdsec example already mounts
/var/lib/crowdsec/data, so the v1.7 strict volume check is already
satisfied (CROWDSEC_BYPASS_DB_VOLUME_CHECK is only required when
running without persistence, as in the E2E suite).

* 🤖 chore: adopt Renovate (weekly, self-hosted) to replace manual version bumps

Automate the kind of bump this PR did by hand. Renovate covers what Dependabot
could not reach here:

- example docker-compose image tags (traefik / crowdsec) — native manager;
- the plugin self-pin (`experimental.plugins.bouncer.version=` in compose args
  and `version:` in the Traefik Helm values) — customManager, github-tags;
- the Crowdsec/Traefik image tags in the Helm values (no `repository` key, so
  matched by file) — customManager, docker;
- the pinned Traefik binary in the e2e mock suite (`TRAEFIK_VERSION`) —
  customManager, github-releases;
- go.mod + GitHub Actions — native managers (this is why we drop Dependabot:
  running both would open duplicate PRs).

Runs weekly via a self-hosted workflow (Mondays 04:00 UTC, plus manual
dispatch). Needs a RENOVATE_TOKEN secret (documented in the workflow). Renovate
PRs trigger the existing e2e CI, so a Traefik/Crowdsec bump is validated to
actually boot and bounce before merge.

* 🔒 ci: pin Go to 1.22 (yaegi ceiling) and cap Renovate's Go updates

The plugin is interpreted by yaegi, bundled in Traefik. Even the latest Traefik
(v3.7.1) ships yaegi v0.16.1, which only supports Go 1.22 — so the plugin's real
ceiling is Go 1.22 on every current Traefik, regardless of the Go version
Traefik itself is built with.

- main.yml: build/test on Go 1.22 (was 1.23) so `go build`/`go test` reject
  newer stdlib early; yaegi v0.16.1 stays the required yaegi_test guard.
- renovate.json: cap the go.mod `go`/`toolchain` directive at `<1.23` so
  Renovate keeps deps/actions/toolchain current but never pushes the plugin
  past what yaegi supports. Raise the cap when Traefik ships a newer yaegi.

* 🐛 ci(renovate): stop ignoring examples/ and tests/ so custom managers run

config:recommended ships a default ignorePaths that excludes **/examples/**
and **/tests/** (and **/vendor/**). That silently disabled 4 of the 5 custom
managers and all example/helm coverage this PR adds — Renovate only saw the
root docker-compose, go.mod and workflows.

Override ignorePaths to keep only vendor/node_modules. Verified via
`renovate --platform=local --dry-run=full`: package files detected go from
7 -> 32, and every custom manager now extracts its dep (plugin self-pin
across 11 compose files, traefik/crowdsec helm tags, e2e TRAEFIK_VERSION pin).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

*  chore: drop one-time example version bumps, let Renovate own them

The manual version catch-up across the example docker-compose files and the
Helm values is now redundant: Renovate (this PR) covers all of them via its
native docker-compose/docker managers plus the custom managers for the plugin
self-pin and the e2e Traefik binary. Reverting these files to keep the PR a
clean "adopt Renovate" change; Renovate will open the bump PRs itself.

Note: examples/tls-auth uses crowdsecurity/crowdsec:latest again — Renovate
does not pin rolling tags, so that one stays floating unless pinned separately.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* 📌 examples(tls-auth): pin crowdsec to v1.6.8 instead of :latest

Rolling `latest` tags aren't reproducible and Renovate can't manage them.
v1.6.8 is already the crowdsec tag used in the root docker-compose files and,
unlike the `-2` build-suffixed tags, Renovate bumps it (→ v1.7.8).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* 📌 examples: normalize crowdsec v1.6.1-2 -> v1.6.8 so Renovate can manage it

Renovate's docker versioning won't advance a build-suffixed tag (v1.6.1-2) to
a clean release (v1.7.8), so those 8 examples would have stayed frozen. v1.6.8
is already used in the root compose files and Renovate bumps it. Also updated
the captcha README snippet to match its compose.

d32f271195 🐛 appsec: do not buffer unreadable (gRPC/HTTP2) request bodies (#332)
* 🐛 fix appsec silently 403-ing gRPC streams with unreadable body

A bidirectional gRPC stream is an HTTP/2 request with no Content-Length
whose body never reaches EOF. Since #321 removed the ContentLength guard,
appsecQuery buffered it with io.ReadAll, which blocked until the request
timed out and was turned into a 403 (issue #323). The backend was never
reached (OriginStatus:0).

Mirror the reference lua-cs-bouncer behaviour: detect an unreadable body
(ProtoMajor >= 2 && ContentLength < 0) and, instead of buffering it,
forward the request to Appsec with headers only. Add a new
CrowdsecAppsecDropUnreadableBody option (default false) that mirrors the
reference APPSEC_DROP_UNREADABLE_BODY: when true, such requests are
blocked outright instead of forwarded without their body.

Readable HTTP/1.1 bodies are still buffered and inspected, so the bypass
closed by #321 stays closed.

* 🚨 appsec: satisfy linters (gocritic ifElseChain, misspell)

mathieuHaandClaude Opus 4.8 f4dcd933c8 🐛 fall back to system trust store when no custom TLS CA is set (#331)
* 🐛 fall back to system trust store when no custom TLS CA is set

Closes #327.

Until now, configuring `crowdsecLapiScheme=https` forced the operator
to either provide `crowdsecLapiTLSCertificateAuthority` (a custom CA)
or set `crowdsecLapiTLSInsecureVerify=true` — there was no way to rely
on the host's system trust store, which is the expected setup when the
LAPI sits behind a reverse proxy with a publicly trusted (e.g. Let's
Encrypt) certificate.

Two contributing bugs:
  - `validateParamsTLS` rejected an empty CA up-front.
  - `getTLSConfig` always allocated an empty `tls.Config.RootCAs`,
    which silently disabled the standard library's fall-back to
    `x509.SystemCertPool()`.

Fix: drop the validation error for the empty-CA case and only allocate
`RootCAs` when a custom CA is actually provided. Same change applies
symmetrically to the AppSec path since the helper is shared.

Add unit tests covering the four meaningful states (HTTP, HTTPS with
system CA, HTTPS with custom CA, HTTPS with insecure verify) plus the
malformed-PEM rejection. README updated to document the system trust
store as an explicit option for both LAPI and AppSec HTTPS.

* 📝 fix gofmt alignment in TLS test struct

*  update existing test: https without CA is now accepted

* ♻️ tests: hoist shared validPEM to package level, rename cfgGarbage

Address review on #331:
- the self-signed validPEM block was duplicated in two test funcs; declare it
  once at package level and drop both local copies.
- rename cfgGarbage -> cfgInvalidCA (and its test case) for a descriptive name.

*  e2e mock: add tls-system-ca scenario (HTTPS LAPI via system trust store)

CI regression coverage for this PR: with no custom CA configured, the bouncer
must fall back to the OS/system trust store for an HTTPS LAPI.

In the binary suite the "system trust store" is whatever Go's
x509.SystemCertPool() reads, which honours SSL_CERT_FILE on the Traefik process.
The scenario mints a throwaway CA, serves the mock LAPI over HTTPS with a cert
signed by it, and runs the stack twice:
  - positive: SSL_CERT_FILE = our CA       -> LAPI trusted    -> 200
  - negative: SSL_CERT_FILE = empty bundle  -> not trusted     -> 403 (fail-closed)
The negative run proves the patch still VERIFIES (not an insecure skip).

- mocklapi: optional --lapi-tls-cert/--lapi-tls-key to serve the LAPI over TLS.
- common.sh: opt-in LAPI_TLS_CERT/KEY (HTTPS mock) and TRAEFIK_SSL_CERT_FILE
  (inject SSL_CERT_FILE into Traefik); both default-empty, other scenarios
  unaffected.
- adds openssl as a scenario-only dependency.

mathieuHaandClaude Opus 4.8 14b9c47ab2 tests: CI end-to-end suite — Traefik binary + mock LAPI (#329)
*  tests: end-to-end suite scaffold + stream-mode scenario

Add tests/e2e/ structure with shared bash helpers and the first
scenario (stream-mode): spin up real Traefik + Crowdsec via docker
compose, mount the repo as a local plugin, add a ban via cscli, verify
the bouncer blocks the matching X-Forwarded-For, then delete the
decision and verify pass-through.

Adds .github/workflows/e2e.yml with one matrix job per scenario
(stream-mode for now), and Makefile targets `e2e` and `e2e_<scenario>`
for local runs.

Refs #328

*  tests: revert to docker provider + bump versions + add 6 scenarios

Reverts the stream-mode scenario to the Traefik docker provider (the
file provider was a workaround for a local docker daemon API version
mismatch, irrelevant in CI). Bumps Traefik to v3.7.1 and Crowdsec to
v1.7.8 across all scenarios.

Adds six new E2E scenarios:
- live-mode: short defaultDecisionSeconds, verifies cache-then-recheck
- none-mode: verifies LAPI is queried per request, no caching
- trusted-ips: clientTrustedIPs bypass even when the trusted IP is banned
- custom-ban-page: BanHTMLFilePath body + Content-Type validation
- captcha: captcha decision serves the captcha page (HTTP 200)
- appsec: SQLi probe blocked by appsec-virtual-patching

Each scenario uses an isolated compose project, mounts the repo as a
local plugin, and asserts behavior via curl. Workflow matrix and
Makefile E2E_SCENARIOS updated accordingly.

Refs #328

* 🐛 tests: set CROWDSEC_BYPASS_DB_VOLUME_CHECK for v1.7+

Crowdsec v1.7 refuses to start without an explicit volume mount on
/var/lib/crowdsec/data (or the bypass env var). For E2E we don't need
db persistence — set the bypass everywhere so the stack boots.

* 🐛 tests: appsec scenario uses OWASP CRS inband collection

appsec-virtual-patching only ships CVE-specific rules, not generic
SQLi. Switch to crowdsecurity/appsec-crs-inband (the blocking OWASP
Core Rule Set) and use a SQLi probe that CRS paranoia level 1
matches (rule 942100/942130).

* ♻️ tests: run e2e suite in a single sequential job

The matrix spawned one runner per scenario, so the Traefik, Crowdsec and
whoami images were pulled — and Crowdsec booted — once per scenario. Run
the whole suite in a single job with `make -k e2e` instead: Docker caches
the images locally so they are pulled only once, and `-k` keeps the
remaining scenarios running after a failure (make still exits non-zero).

Scenarios already share the canonical `crowdsec` container name and the
8000 port, so they were meant to run sequentially anyway.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

*  tests: add binary e2e suite (Traefik binary + Go mock LAPI), run it in CI

Add a second e2e suite that runs Traefik as a downloaded binary with the
plugin loaded from source, and replaces Crowdsec with a small stdlib-only Go
LAPI mock driven via /admin endpoints. No Docker, no real Crowdsec.

The mock lives in its own nested Go module (tests/e2e/mock/mocklapi) so it
stays out of the plugin module's build, lint, test and vendor.

This suite validates the plugin's own behaviour (live/none/stream modes,
caching, trusted-IP bypass, ban/captcha rendering). Crowdsec and AppSec
correctness are out of scope on purpose — they are validated upstream by the
maintainer — so the AppSec scenario is intentionally absent and the README
says so to avoid misfiled issues.

CI now runs this suite only (`make e2e_mock`), since it needs neither Docker
nor a real Crowdsec. The Docker suite (tests/e2e/scenarios) is kept for local
debugging (`make e2e`).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* 🔧 e2e mock: address review — clarify backend flag, move ignore to root

- Document the --backend-addr flag: it is the stub upstream service Traefik
  proxies allowed requests to (the traefik/whoami equivalent), not AppSec.
- Move the .cache/ ignore rule from the per-suite .gitignore to the repo root
  .gitignore, and make the wording accurate: the cache persists across local
  runs but is recreated on every (fresh-runner) CI run.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* ♻️ tests: move local Docker e2e suite to its own PR (#333)

Per review, split the e2e work so each PR is focused. CI runs the binary +
mock-LAPI suite (this PR); the heavier, local-only Docker suite (real Traefik
+ Crowdsec, incl. appsec) now lives in #333.

Removes tests/e2e/scenarios, tests/e2e/lib and the Docker-suite README, and
drops the `e2e` Make target here (kept in #333). The binary/mock suite and its
`e2e_mock` target are unchanged.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* 🔥 e2e mock: simplify the Crowdsec LAPI mock

Per review, trim the mock to the minimum the plugin actually exercises:

- Drop the stream delta bookkeeping (startup flag + "already streamed" set).
  The plugin re-Sets/Deletes its cache on every poll, so reporting the whole
  active set as "new" and removed ones as "deleted" is enough.
- Shrink the Decision struct to the three fields the plugin reads
  (value/type/duration); drop id/origin/scope/scenario and the id counter.
- Drop API-key auth and the /admin/reset endpoint — no scenario exercises
  either. Also drop the now-unused lapi_reset helper.
- Replace the store struct + methods with two package-level maps + a mutex.

mocklapi/main.go: 234 -> 118 lines. All six scenarios still pass.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

*  e2e mock: replace fixed sleeps with condition polling

The `sleep 4` / `sleep 3` after a decision change were magic numbers tied to
updateIntervalSeconds / defaultDecisionSeconds. Replace them with waits on the
actual condition:

- After a ban/unban, poll with wait_for_status until the expected code shows up
  (stream propagation / live-mode cache TTL).
- Captcha keeps status 200 before and after, so gate on the body marker via a
  new wait_for_body_contains helper.
- Control assertions that must NOT change stay immediate (assert_status).

Self-documenting, faster on the happy path (returns on the first poll that
sees the change), and more robust under slow CI. No fixed sleeps remain.

* ⬆️ e2e mock: bump module go directive to 1.23

Align the mock module with the project's Go version (CI uses 1.23). Part of
standardising the whole project on Go 1.23; the plugin module is bumped
separately.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* ⬇️ e2e mock: keep Go floor at 1.22 (yaegi ceiling)

Revert the mock module back to go 1.22 and make the e2e workflow read the Go
version from go.mod (go-version-file) instead of hardcoding 1.23.

Rationale: the plugin is interpreted by yaegi, and even Traefik v3.7.1 ships
yaegi v0.16.1 (Go 1.22), so the project stays on 1.22. The earlier bump to 1.23
is dropped (plugin go.mod stays 1.22, see #330 for the Renovate cap + CI pin).
Mock + all six scenarios verified on Go 1.22.

*  e2e mock: add AppSec scenario + custom remediation header assertion

Address review feedback on the binary e2e suite:

- mocklapi: add an AppSec WAF stand-in (--appsec-addr) that blocks any URI
  containing "rpc2" — the exact probe from examples/appsec-enabled — and allows
  the rest. Lets the suite exercise the plugin's AppSec wiring (header
  forwarding + allow/block enforcement) without the real CRS engine.
- new scenarios/appsec: benign request passes, /foo/rpc2 is 403.
- custom-ban-page: assert the banned response carries the custom remediation
  header (remediationHeadersCustomName), per review.
- README: drop the "don't open issues / AppSec intentionally absent" framing;
  describe what the suite actually covers, including AppSec wiring.

mathieuHaandClaude Opus 4.8 f5d580578c 📝 docs: fix Mermaid diagrams not rendering (lowercase destroy keyword) (#335)
The sequence diagrams used the keyword `Destroy` (capital D). Mermaid
keywords are case-sensitive, so the invalid token aborted parsing and
every diagram failed to render on GitHub.

Lowercase all `Destroy` -> `destroy` in README.md and the captcha
example README. The `create` keyword was already correct, and each
create/destroy is properly paired with an adjacent message.

Fixes #270

maxlerebourgandmhx 71d845faae ️ Do not block middleware startup due to stream intialization (#281)
* 🍱 not block on stream startup

* 🍱 fix

* 🍱 fix lint

* 🍱 fix lint

* 🍱 fix lint

* 🍱 update readme

* 📚 clarify StreamStartupBlock warning in README

Make the fail-open implication of StreamStartupBlock=false explicit:
banned IPs are allowed through until the first stream sync completes.

* 🐛 clear isCrowdsecStreamStartup on alreadyUpdated path

When cacheTimeoutKey is already set (another instance/process has
populated the stream cache within the update window), the early return
in handleStreamCache used to leave isCrowdsecStreamStartup at true,
causing this instance to keep sending startup=true on subsequent ticks.
Flip the flag in the early-return path so startup is correctly tracked
across multi-instance deployments sharing a cache.

Remediation offered by [Crowdsec](https://docs.crowdsec.net/u/bouncers/intro) and supported by the plugin can be either `ban` or `captcha`.
For the `ban` remediation the user will be blocked in Traefik (HTTP 403).
For the `captcha` remediation, the user will be redirected to a page to complete a captcha challenge.
There are 4 operating modes (CrowdsecMode) for this plugin: On successfull completion, he will be cleaned for a specified period of time before a new resolution challenge is expected if Crowdsec still has a decision to verify the user behavior. See the example captcha for more informations and configuration intructions.
The following captcha providers are supported now:
| Mode | Description | - [hcaptcha](https://www.hcaptcha.com/)
|------|------| - [recaptcha](https://www.google.com/recaptcha/about/)
| none | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual. All request call the Crowdsec LAPI | - [turnstile](https://www.cloudflare.com/products/turnstile/)

The bouncer can leverage use of a local cache in order to reduce the number of requests made to the Crowdsec LAPI. It will keep in cache the status for each IP that makes queries. | - [custom/wicketkeeper](https://github.com/a-ve/wicketkeeper)

**/!\ Cache is shared by all services** > [!IMPORTANT]
*This means if an IP is banned, all services which are protected by an instance of the plugin will deny requests from that IP* > Some of the behaviours and configuration parameters are shared globally across _all_ crowdsec middlewares even if you declare different middlewares with different settings.

> **Cache is shared by all services**: This means if an IP is banned, all services which are protected by an instance of the plugin will deny requests from that IP
>
> If you define different caches for different middlewares, only the first one to be instantiated will be bound to the crowdsec stream.
>
> Overall, this middleware is designed in such a way that **only one instance of the plugin is _possible_.** You can have multiple crowdsec middlewares in the same cluster, the key parameters must be aligned (MetricsUpdateIntervalSeconds, CrowdsecMode, CrowdsecAppsecEnabled, etc.)

#### Use HTTPS to communicate with the LAPI #### Use HTTPS to communicate with the LAPI
To communicate with the LAPI in HTTPS you need to either accept any certificates by setting the `crowdsecLapiTLSInsecureVerify` to true or add the CA used by the server certificate of Crowdsec using `crowdsecLapiTLSCertificateAuthority` or `crowdsecLapiTLSCertificateAuthorityFile`. Set `crowdsecLapiScheme` to `https`. The plugin then validates Crowdsec's server certificate. Three options:
Set the `crowdsecLapiScheme` to https.
- **Publicly trusted certificate** (e.g. Let's Encrypt behind a reverse proxy): leave `crowdsecLapiTLSCertificateAuthority` empty and `crowdsecLapiTLSInsecureVerify` `false`. The plugin falls back to the host's system trust store (the `traefik` image ships `ca-certificates`).
- **Private/self-signed CA**: set `crowdsecLapiTLSCertificateAuthority` (or `…File`) to the PEM-encoded CA that signed Crowdsec's server cert.
- **Skip verification entirely** (not recommended for production): set `crowdsecLapiTLSInsecureVerify` to `true`.

#### Use HTTPS to communicate with the Appsec
Set `crowdsecAppsecScheme` to `https`. Same three options as for the LAPI, prefixed `crowdsecAppsec…` instead of `crowdsecLapi…`: empty CA + secure verify falls back to the system trust store, a custom CA pins to your private PKI, and `crowdsecAppsecTLSInsecureVerify=true` skips verification altogether.
Currently AppSec does not support mTLS authentication for the AppSec Component.

# Example
## Enabling catpcha response from crowdsec
Crowdsec support 3 remediations solutions `ban`, `captcha`, and `throttle`.
This plugins support the `ban` and `captcha` remediation.
### Traefik configuration
The minimal configuration is defined below.
For now 3 captcha providers are supported:
- [hcaptcha](https://www.hcaptcha.com/)
- [recaptcha](https://www.google.com/recaptcha/about/)
- [turnstile](https://www.cloudflare.com/fr-fr/products/turnstile/)
```yaml
labels:
# Choose captcha provider
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaProvider=hcaptcha"
# Define captcha site key
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaSiteKey=FIXME"
# Define captcha secret key
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaSecretKey=FIXME"
# Define captcha grace period seconds
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaGracePeriodSeconds=1800"
# Define captcha HTML file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaHTMLFilePath=/captcha.html"
```
The captcha HTML file must be present in the Traefik container (bind mounted or added during a custom build).
It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/captcha.html) it locally to expose it to Traefik.
```yaml
...
traefik:
image: "traefik:v3.0.0"
volumes:
- './captcha.html:/captcha.html'
...
```
### Crowdsec configuration
Crowdsec by default will take the ban action on suspicious activity detected in logs.
To instruct Crowdsec to use captcha remediation, change the `/etc/crowdsec/profiles.yaml`.
2 modes are supported:
- Always return a captcha decision
- Return a captcha decision the first X times and then a ban decision.
The second mode could be used to prevent repeated malicious activity.
More information is available on configuring Crowdsec in the [official documentation](https://docs.crowdsec.net/docs/next/local_api/profiles/captcha_profile/).
```yaml
...
crowdsec:
image: crowdsecurity/crowdsec:v1.6.8
volumes:
# For captcha and ban mixed decision
- './profiles.yaml:/etc/crowdsec/profiles.yaml:ro'
# For captcha only remediation
# - './profiles_captcha_only.yaml:/etc/crowdsec/profiles.yaml:ro'
...
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type captcha
```
![image decision captcha](image_decision_captcha.png)
We will see in the browser the captcha validation page:
![image captcha validation](image_captcha_validation.png)
To play the demo environment run:
```bash
make run_captcha
```
> Note, if we are banned with a "ban" decision from crowdsec a captcha will not be asked and you will have to wait for the decision to expire or remove it manually.
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.10 -d 10m --type ban
```
## Captcha Workflow

# Example
## Adding a custom ban page
Traefik can return a custom HTML ban page along with the 403 HTTP response code.
This can be usefull as some browser (Firefox for instance) return a 403 blank webpage and we can mistake a server/reverse-proxy error with a ban from Crowdsec.
### Traefik configuration
```yaml
labels:
# Define ban file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.banFilePath=/ban.html"
```
The ban file must be present in the Traefik container (bind mounted or added during a custom build).
It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/ban.html) it locally to expose it to Traefik.
```yaml
...
traefik:
image: "traefik:v2.11.0"
volumes:
- './ban.html:/ban.html'
...
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type ban
```
![image decision ban](image_decision_ban.png)
We will see in the browser the ban custom page:
To play the demo environment run:
```bash
make run_custom_ban_page
```
## Another thing to note
In the html of the ban page, you can use:
- {{ .ClientIP }} to display the IP used to ban the request.
- {{ .RemediationReason }} that convert on runtime into why the ban page is served. It's an enum with "APPSEC", "LAPI", "TECHNICAL_ISSUE" and it is useful to help user understand why the request is blocked.
- {{ .CustomHeader }} value of the specified Request Header (for example X-Request-ID)
```
<script>var remediation = "{{ .RemediationReason }}"</script>
<script>var clientIp = "{{ .ClientIP }}"</script>
<script>var traceID = "{{ .TraceID }}"</script>
```
With the above tweak and some other js, you can customize your ban page on runtime.

# Example
Read the example captcha before this, to better understand what is done here.
### Traefik configuration
The minimal configuration is defined below to implement custom captcha.
This documentation use https://github.com/a-ve/wicketkeeper, a self-hosted captcha provider that have a similar API than big providers.
Minimal API requirement:
- the JS file URL to load the captcha on the served `captcha.html`
- the HTML className to tell to the JS where to display the challenge
- the verify URL endpoint to send the field `response` from the captcha with `content-type: application/x-www-form-urlencoded`
- the name of the field when you POST the resolved captcha to Traefik
- the JS file need to respect the `data-callback` on the div that contains the captcha if you use our template, but you can customize it by your side
```yaml
traefik:
...
labels:
# Choose captcha provider
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaProvider=custom"
# Define captcha grace period seconds
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaGracePeriodSeconds=1800"
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaCustomJsURL=http://captcha.localhost:8000/fast.js"
# Inside Traefik container the plugin must be able to reach wicketkeeper service so we can go through a Traefik localhost
# domain which would resolve traefik itself and the port for the dashboard
- "traefik.http.middlewares.crowdsec.plugin.bouncer.CaptchaCustomValidateURL=http://wicketkeeper:8080/v0/siteverify"
- "traefik.http.middlewares.crowdsec.plugin.bouncer.CaptchaCustomKey=wicketkeeper"
- "traefik.http.middlewares.crowdsec.plugin.bouncer.CaptchaCustomResponse=wicketkeeper_solution"
# Define captcha HTML file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaHTMLFilePath=/captcha.html"
```
```yaml
wicketkeeper:
image: ghcr.io/a-ve/wicketkeeper:latest
user: root
ports:
- "8080:8080"
environment:
- LISTEN_PORT=8080
- REDIS_ADDR=redis:6379
- DIFFICULTY=4
- ALLOWED_ORIGINS=*
- PRIVATE_KEY_PATH=/data/wicketkeeper.key
volumes:
- ./data:/data
depends_on:
- redis
redis:
image: redis/redis-stack-server:latest
```
```html
<div id="captcha" class="{{ .FrontendKey }}" data-sitekey="{{ .SiteKey }}" data-callback="captchaCallback" data-challenge-url="http://captcha.localhost:8000/v0/challenge">
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself and retry.
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 10m --type captcha
```
To play the demo environment run:
```bash
make run_custom_captcha
```

## Separate LAPI and Appsec HTTP/S config
To separate TLS config for LAPI and Appsec, you can use all the TLS LAPI variable beginning with `CrowdsecLapi...` into `CrowdsecAppsec...`.
Don't forget to set `CrowdsecAppsecScheme: HTTP` or `HTTPS` to trigger the separate setup.

# Binary e2e suite (Traefik binary + mock LAPI)
This suite runs **Traefik as a downloaded binary** with the plugin loaded from
the local source tree, and replaces Crowdsec with a small **HTTP mock**
([`mocklapi/`](mocklapi/main.go), a stdlib-only Go command). No Docker, no real
Crowdsec.
It is what **CI runs** (`make e2e_mock`). A separate, local-only **Docker
suite** (real Traefik + Crowdsec, under `tests/e2e/scenarios`) is kept for
high-fidelity debugging against a real Crowdsec but is not exercised in CI; it
ships in its own PR (#333).
## Scope — what this suite tests
These tests validate the **plugin's own behaviour**: the request flow through
the Traefik middleware, the live / none / stream modes, caching, trusted-IP
bypass, ban / captcha page rendering, and the AppSec request path (header
forwarding + enforcing the engine's allow/block verdict).
The mock stands in for Crowdsec, emulating the slice of the LAPI HTTP contract
the plugin consumes — including a single, deterministic AppSec rule (block any
URI containing `rpc2`, the probe from [`examples/appsec-enabled`](../../../examples/appsec-enabled)).
It is not the real WAF engine, so this suite exercises the plugin's AppSec
*wiring* rather than the detection accuracy of OWASP CRS / virtual patching —
that lives upstream in Crowdsec.
## What runs
| Component | How |
|-----------|-----|
| Traefik | Binary `v3.7.1`, downloaded into `.cache/` (reused across local runs; re-downloaded on fresh CI runners) |
| Plugin | Loaded via `experimental.localPlugins` from the repo root (symlinked into `plugins-local/`) |
| LAPI | `mocklapi` — a stdlib-only Go command (its own nested module), compiled and cached under `.cache/`, driven through `/admin` endpoints instead of `cscli`. Serves plain HTTP, or HTTPS when `--lapi-tls-cert/--lapi-tls-key` are passed (the `tls-system-ca` scenario) |
| AppSec | WAF stand-in built into the mock — blocks URIs containing `rpc2`, allows the rest |
| Backend | A plain HTTP responder built into the mock |
Fixed ports (override with env vars if needed): Traefik `8000`, LAPI `8090`,
backend `8091`, AppSec `8092`.
## Running locally
Prerequisites: `bash`, `curl`, `go`, `tar` (plus `openssl` for the
`tls-system-ca` scenario, which mints a throwaway CA at runtime). On first use
the Traefik binary is fetched and the mock is compiled into `.cache/`. That
cache is reused across local runs; CI runs on fresh runners, so both are
recreated on every CI run.
The `tls-system-ca` scenario verifies that, with no custom CA configured, the
bouncer falls back to the OS/system trust store for an HTTPS LAPI: it serves the
mock over TLS and points the Traefik process's `SSL_CERT_FILE` at the test CA
(trusted → 200) or an empty bundle (untrusted → 403, proving it still verifies).
```bash
# one scenario
make e2e_mock_stream-mode
# or directly
./tests/e2e/mock/scenarios/stream-mode/run.sh
# the whole suite
make e2e_mock
```
## Layout
```
mock/
lib/
common.sh # stack lifecycle, Traefik download, mock build, assertions, admin client
traefik.yml # static Traefik config (shared by all scenarios)
mocklapi/
go.mod # nested module — kept out of the plugin's build/lint/vendor
main.go # mock LAPI + AppSec stand-in + backend
scenarios/
<name>/
dynamic.yml # Traefik dynamic config (router + bouncer middleware + backend)
run.sh # assertions for the scenario
*.html # optional fixtures (ban / captcha templates)
```
`dynamic.yml` uses placeholders (`@@APIKEY@@`, `@@LAPI_HOST@@`,
`@@BACKEND_URL@@`, `@@SCENARIO_DIR@@`) that `common.sh` substitutes at runtime.
## Adding a scenario
1. Create `scenarios/<name>/dynamic.yml` and `run.sh` (copy `stream-mode/` as a
template).
2. In `run.sh`, define a `body` function with the assertions and call
`run_scenario "<name>" "$HERE" body`.
3. Drive decisions with `lapi_add_decision <ip> [type] [duration]` and
`lapi_delete_decision <ip>`.
4. Add `<name>` to `E2E_MOCK_SCENARIOS` in the `Makefile`.
