security: remediate audit findings (ranks 1–16 + 22 Lows) + yaegi load validation (#144)
* fix(security): encrypt session cookies + fail closed on invalid config
Batch 1 of security audit remediation (ranks 1, 2, 6).
- session.go: derive independent HMAC + AES-256 keys via stdlib HKDF-SHA256
and build the gorilla cookie store with both, so session cookies are now
encrypted, not merely signed. The single-key store previously left OIDC
access/refresh/ID tokens recoverable from raw cookie bytes. Cookie format
changes, so existing sessions are invalidated on deploy (one-time re-login).
- main.go: call config.Validate() at construction and error out on failure,
instead of silently substituting a public hardcoded encryption key for
empty/short keys (which allowed session forgery). The yaegi analyzer
passes via .traefik.yml testData.
- settings.go: isValidSecureURL permits plaintext HTTP for loopback hosts
only (RFC 8252); remote providers must still use HTTPS.
- tests: complete configs that did not satisfy Validate(); add regression
tests in security_audit_fixes_test.go.
Configs below documented minimums (rateLimit < 10, key < 32 chars) are now
rejected at startup (fail closed).
* fix(security): validate discovered OIDC endpoints + pin introspection host
Batch 2 of security audit remediation (ranks 3, 4).
- url_helpers.go: add validateDiscoveredEndpoint, an SSRF screen for endpoints
taken from the provider discovery document (jwks_uri, token, authorization,
revocation, end_session, introspection, registration). Blocks link-local
(cloud metadata 169.254.169.254), multicast, unspecified and private
addresses (unless allowPrivateIPAddresses); blocks loopback unless the
configured providerURL is itself loopback (dev/test). Cross-domain JWKS
hosts (e.g. Google) stay allowed. Add sameHost helper.
- main.go: updateMetadataEndpoints screens every discovered endpoint and
blanks any that fail (fail closed downstream). The introspection endpoint
carries the client secret via HTTP Basic, so it is additionally pinned to
the providerURL host to stop a poisoned discovery document exfiltrating the
secret to an attacker-controlled host.
- tests: regression tests for the SSRF guard and the host pin.
* fix(security): close open redirects + anchor excluded-URL matching
Batch 3 of security audit remediation (ranks 5, 14, 15).
- auth_flow.go: run the stored incoming path through normalizeLogoutPath
before using it as the post-login redirect, so //evil.com and /\evil.com
payloads become host-relative (open-redirect, rank 5).
- url_helpers.go: excluded-URL matching is anchored at a natural boundary
(exact, sub-path "/", or file extension "."), so excluding "/public" no
longer also bypasses auth on "/publicsecret"; "/favicon" still matches
"/favicon.ico" (rank 14).
- internal/utils: X-Forwarded-Host is sanitized (first value only; reject
CRLF/whitespace/multi-value) before building redirect URLs (rank 15).
- helpers.go: the logout redirect used when there is no provider end-session
endpoint is host-relative, never an absolute URL derived from the
client-controllable request host (logout open-redirect, rank 15).
- tests: update two logout cases that asserted the old absolute redirect;
add regression tests.
* fix(security): reject unverified Azure tokens; fix transport TLS reuse
Batch 4 of security audit remediation (ranks 7, 11).
- token_validation_rs.go: an Azure nonce-bearing access token that cannot be
cryptographically verified no longer returns "authenticated" when there is
no ID token to corroborate it; it refreshes (if possible) or forces
re-authentication instead of failing open (rank 7).
- http_client_pool.go: the at-limit transport-reuse path now takes the write
lock before mutating refCount (fixes a data race) and only reuses a
transport whose TLS settings (CA pool + InsecureSkipVerify) match the
caller's, never one with a different trust store; if none matches it returns
nil so the caller falls back to a verifying default transport (rank 11).
- tests: add a transport-pool TLS-isolation regression test.
* fix(security): stop logging templated header values (token leak)
Batch 5 of security audit remediation (rank 16).
middleware.go: templated downstream headers commonly carry the access token
(e.g. "Authorization: Bearer {{.AccessToken}}"). The debug log line printed
the full header value, leaking credentials into logs. Log the header name and
byte length instead.
* fix(security): cache-key collision, cache-config divergence, fleet cleanup
Batch 6 of security audit remediation (ranks 9, 10, 12).
- token_manager.go: detectTokenType keys its cache on a SHA-256 hash of the
full token instead of the first 32 chars (which are only the base64url JWT
header). Distinct tokens sharing alg+kid no longer collide and get
mis-classified (rank 10).
- cache_manager.go: the process-global cache manager is initialized once and
shared across plugin instances; it now logs a loud warning when a later
instance requests a different explicit Redis backend that is silently
ignored, surfacing the cross-instance state-isolation hazard (rank 9).
- singleton_resources.go / main.go / utilities.go: track a process-global live
instance count; the shared singleton-token-cleanup task is stopped only when
the LAST instance shuts down, so one instance's Close() (e.g. a config reload)
no longer kills cleanup for surviving instances (rank 12).
- tests: update TestDetectTokenTypeCaching for the new key; add regression tests.
* fix(security): bound introspection cache + cookie lifetime to config
Batch 7 of security audit remediation (ranks 8, 13).
- token_introspection.go: when requireTokenIntrospection is enabled, cap the
positive introspection-result cache at 30s (instead of 5m) so a token
revoked at the provider stops passing within ~30s, matching the operator's
near-real-time revocation expectation (rank 8).
- session.go: bind the cookie store's MaxAge to the configured sessionMaxAge,
so the cookie codec's cryptographic timestamp validity is no longer fixed at
gorilla's 30-day default; a stolen cookie is valid only for the configured
session lifetime (rank 13).
- tests: add a cookie-lifetime regression test.
* fix(security): low-severity hardening (cache, DoS caps, PKCE, throttle)
Batch 8 of security audit remediation — low severity
(ranks 24, 25, 27, 29, 31, 36, 37, 41, 45, 46, 49).
- universal_cache.go: updateLocalCache updates an existing key in place instead
of orphaning its LRU element and double-counting currentSize/currentMemory
(rank 36 — the only production-reachable bug in this batch).
- jwk.go / metadata_cache.go / token_introspection.go: bound response bodies
with io.LimitReader (1 MiB) to prevent memory exhaustion from a hostile or
buggy provider (ranks 24, 25).
- jwk.go: skip JWKs not usable for signature verification (use != sig, or
key_ops without "verify") when building the key set (rank 49).
- auth_flow.go: fail closed at the callback when PKCE is enabled but the code
verifier is missing, instead of silently dropping it (rank 27).
- utilities.go / main.go: match allowedUserDomains case-insensitively (rank 31).
- bearer_auth.go: a single success no longer wipes an active per-IP penalty;
the counter resets only when no penalty is in effect (rank 29).
- main.go: handle (not discard) the NewSessionManager error (rank 37).
- error_recovery.go: take a write lock in isServiceDegraded (it deletes from a
map); compare retryable-error substrings case-insensitively (ranks 45, 46).
- singleton_resources.go: bind the generic-cache cleanup goroutine to the
resource-manager shutdown channel so it cannot outlive its owner (rank 41).
- tests: update the bearer throttle test to the corrected penalty semantics.
* fix(security): header sanitization, issuer pinning, fail-closed paths
Batch 9 of security audit remediation (ranks 18, 19, 20, 21, 22, 30, 33, 34).
- middleware.go / bearer_auth.go: sanitize claim-derived values on the cookie
auth path before injecting them into downstream headers. Drop group/role and
identifier values containing control chars, bidi-override runes, or the
, ; = delimiters (a comma would inject phantom entries into X-User-Groups);
reject control/bidi/over-length in rendered templated header output (but
permit , ; = in free-form values such as a bearer token). The bearer path
already sanitized; the cookie path did not (ranks 33, 34).
- main.go / metadata_cache.go: pin the discovered issuer to the configured
provider host (sameHost) and refuse/never-cache a mismatch, so a poisoned
discovery document cannot redefine the JWT trust anchor (ranks 21, 22).
- token_introspection.go: when a distinct API audience is configured, fail
closed on a missing or mismatched introspection audience; aud parsed as
string-or-array per RFC 7662 (rank 19).
- logout.go: front-channel logout requires a matching issuer; an empty iss is
rejected (blocks unauthenticated forced-logout via a known sid) (rank 30).
- token_validation_rs.go: an opaque access token with no ID token and no
successful introspection fails closed (re-auth) instead of authenticating
(ranks 18, 20).
- tests: realistic same-host provider mocks; regression tests for the header
sanitization distinction and the fail-closed paths.
* chore(security): remove unwired dead code with latent footguns
Batch 10 of security audit remediation — delete confirmed-dead, unwired
subsystems (ranks 26, 35, 50). None had a production caller (grep-verified);
removal eliminates the latent footguns and ~2.1k lines of dead code.
- token_validator.go (deleted): an unused *TokenValidator whose validateJWT set
Valid=true with NO signature verification — a severe footgun if ever wired
(rank 50). The wired RS-aware validators are unaffected.
- security_monitoring.go (deleted): an unused *SecurityMonitor / ExtractClientIP
that trusted spoofable X-Forwarded-For / X-Real-IP. The live bearer throttle
uses clientIPForBearer (RemoteAddr-only), unchanged (rank 35).
- dynamic_client_registration.go: removed the RFC 7592 management methods
(Update/Read/DeleteClientRegistration) that dereferenced an attacker-
influenced RegistrationClientURI with the registration token attached and no
HTTPS/SSRF gate, and had no callers. The wired RFC 7591 RegisterClient and
credential-store helpers are kept (rank 26).
- tests: removed the tests covering the deleted code.
* chore: add Makefile with yaegi load validation
No Makefile existed. The new `yaegi-validate` target interprets the plugin
under the yaegi interpreter the same way Traefik loads it, catching yaegi-only
incompatibilities (unsupported stdlib symbols, reflection edge cases) that the
native `go build` / `go test` toolchain does not. Importing the plugin forces
yaegi to interpret every file plus its vendored deps; CreateConfig + New
exercise the instantiation path.
- cmd/yaegicheck/main.go: the load driver, marked //go:build ignore so it is
excluded from `go build ./...` (avoids VCS-stamping a main binary, which
fails in git-worktree layouts) yet is run explicitly by yaegi.
- Makefile: build / fmt / vet / lint / test / vendor / yaegi-validate / check
targets; `make check` runs vet + tests + yaegi-validate.
Verified: `make yaegi-validate` passes on this branch — the HKDF cookie
encryption, net-based endpoint validation, and claim sanitizers all interpret
and instantiate cleanly under yaegi.
* ci: bump workflow Go toolchain to 1.25; pin yaegi-validate to v0.16.1
Traefik v3.7.1 (the deployed version) is built with `go 1.25.0`, so the PR and
release workflows now use Go 1.25.x to match the toolchain Traefik uses.
Important distinction: the CI Go version is the build TOOLCHAIN. The plugin's
actual interpreter-compatibility ceiling is the yaegi version Traefik bundles
(v0.16.1, which declares go 1.21 and ships a ~Go 1.22 stdlib symbol surface),
NOT the CI Go version. That ceiling is enforced by `make yaegi-validate` plus
the go.mod language directive — e.g. it is why HKDF is hand-rolled with
hmac+sha256 rather than Go 1.24's crypto/hkdf, which yaegi v0.16.1 lacks.
Also pin Makefile YAEGI_VERSION to v0.16.1 (what Traefik v3.7.1 vendors) so
yaegi-validate exercises the real deployed interpreter instead of @latest,
which could pass on a newer yaegi that supports symbols the deployed one does
not.
* docs: align README/CONFIGURATION with branch behavior changes
- excludedURLs: documented as segment/extension-boundary matching (was
"prefix-matched") — "/public" no longer also matches "/publicsecret" (rank 14).
- Front-channel logout now requires a matching `iss`; requests without one are
rejected with 400 (rank 30).
- Add an "Upgrading from an earlier release" note: session cookies are now
AES-256 encrypted with lifetime tracking sessionMaxAge (one-time re-login on
upgrade), and invalid configuration (rateLimit < 10, key < 32 bytes, missing
callbackURL, non-HTTPS remote providerURL) now fails closed at startup.
* fix: remove staticcheck-flagged unused functions; wire staticcheck into make check
CI Static Analysis (standalone staticcheck) failed with U1000 "unused":
- dynamic_client_registration.go: deleteCredentialsFromStore — its only caller
was the RFC 7592 DeleteClientRegistration removed in the dead-code batch.
- token_test.go: createTestJWTSimple — its only callers were the TokenValidator
tests removed in the same batch.
Both confirmed to have zero remaining callers and removed. build / vet /
go test ./... / staticcheck ./... all green.
The pre-commit hook runs golangci-lint, but CI runs standalone staticcheck
(which flags U1000). Add a `staticcheck` Makefile target and include it in
`make check` so this class of finding is caught locally before push.
* fix(test): stabilize flaky TestWorkerPool_TaskPanic
tasksFailed is incremented in the worker's deferred recover(), which runs after the panicking task's own defer wg.Done(). wg.Wait() could therefore return before the failure was recorded, so reading the counter immediately raced and flaked on slow CI runners. Poll until the failure lands (2s budget) instead. Verified 200x plain + 50x under -race/GOMAXPROCS=1.

fix(refresh): coalesce refresh-token grants + bound goroutines + cache hot path (target v0.8.27) (#131)
* fix(refresh): wire RefreshCoordinator into the live refresh path
The RefreshCoordinator existed but was never instantiated. The actual
refresh path used only session.refreshMutex, which is per-SessionData
instance - and SessionData is pulled from a sync.Pool per request -
so concurrent requests sharing a refresh token had ZERO coordination.
Symptom: when access_token expired (e.g. 5min Zitadel default), every
in-flight request from a polling client (Grafana panels) entered the
refresh path simultaneously and POSTed the same refresh_token to the
IdP. With refresh-token rotation enabled (Zitadel/Authentik default),
only one grant succeeded; the rest got invalid_grant and each cleared
the entire session. Subsequent requests then thrashed in re-auth loops.
This commit:
- adds refreshCoordinator field on TraefikOidc
- instantiates it in NewWithContext with DefaultRefreshCoordinatorConfig
- shuts it down in Close() under shutdownOnce
- routes refreshToken() through the coordinator via coordinatedTokenRefresh,
which collapses concurrent grants to a single upstream call per
refresh_token hash
- exports refreshCoordinatorSessionID for both internal hashing and the
middleware-level wireup so dedup keys stay aligned
Behavioural notes:
- nil-coordinator fallback preserves existing tests that build TraefikOidc
literals without going through the constructor
- followers receive the same TokenResponse/error as the leader, so no
per-instance code paths change
- existing TestGetNewTokenWithRefreshToken_Concurrency still passes
because it hits GetNewTokenWithRefreshToken directly, below the
coordinator boundary
Tests:
- refresh_coordinator_wireup_test.go: 50 concurrent refreshes coalesce
to <=2 upstream calls; distinct tokens still run in parallel; nil
coordinator falls back cleanly
* perf(cache): bound L1 backfill goroutines in HybridBackend
Get() and GetMany() previously spawned a goroutine per L2 hit to write
the value through to L1. Under sustained polling traffic (e.g. a Grafana
dashboard refreshing every 30s with N panels) this minted thousands of
goroutines, each running in Yaegi - directly contributing to the
~1000% CPU spike that pairs with the refresh-token herd.
Replace the per-hit goroutines with a single l1BackfillWorker fed by
l1BackfillBuffer, mirroring the existing asyncWriteBuffer/asyncWriteWorker
pattern for L2 writes. Buffer overflow drops the backfill (counted via
l1BackfillDrops) - a dropped backfill just means the next L2 hit for
that key re-queues it, which is safe.
Tests:
- TestHybridBackend_L1BackfillBounded: 1000 distinct L2 hits keep
goroutine count within +20 of baseline (pre-fix it grew by ~1000)
- TestHybridBackend_L1BackfillFullDrops: drops are accounted for when
the buffer is saturated and the worker is stopped
* feat(refresh): implement isRefreshTokenExpired heuristic
Replace the placeholder `return false` with a real check based on the
issued_at timestamp that SetRefreshToken already stamps into the session.
Gated by a new MaxRefreshTokenAgeSeconds config field (default 21600 =
6h, matching the existing comment). 0 disables the check.
This wires the previously-dead refreshTokenExpired branch in middleware.go,
which short-circuits AJAX requests with a 401 instead of letting them
hammer the IdP for a refresh token that's almost certainly stale - the
classic Grafana-after-long-pause failure mode.
Behaviour:
- maxRefreshTokenAge=0 disables the check (preserves prior behaviour)
- legacy sessions without issued_at still attempt one refresh; the IdP
remains the source of truth on first try
- nil-receiver and nil-session guards keep test code that builds
TraefikOidc literals safe
Tests:
- TestIsRefreshTokenExpired_DisabledWhenAgeZero
- TestIsRefreshTokenExpired_LegacySessionWithoutTimestamp
- TestIsRefreshTokenExpired_WithinWindow
- TestIsRefreshTokenExpired_BeyondWindow
- TestIsRefreshTokenExpired_NilGuards
* perf(token): skip parseJWT on cache hit in VerifyToken
The token cache fast-return existed but ran AFTER parseJWT, so every
validation paid for base64 + JSON unmarshal even on a hit. Under bursty
traffic (e.g. 10+ concurrent panel requests on every Grafana dashboard
refresh, each calling validateStandardTokens which verifies BOTH the
access token and the ID token), this is two redundant parses per
request multiplied by the panel count.
Move the cache lookup ahead of parseJWT. On a hit the function returns
nil immediately. On a miss the original flow runs unchanged.
Also nil-guard t.tokenCache to keep partial-literal test instances safe
(matches the same pattern we already use for tokenBlacklist).
Tests:
- TestVerifyToken_CacheHitSkipsParse: cache pre-populated with claims
for a token whose body would fail parseJWT - returns nil iff the
fast-path bypasses the parse
- TestVerifyToken_CacheMissStillParses: a syntactically valid but
unsigned token still errors past parseJWT on cache miss
* feat(refresh): cross-replica refresh-grant dedup via shared cache
The in-process RefreshCoordinator added in
