patch-release
The refresh path in token_manager.go hardcoded the "email" claim when
extracting the user identifier from a refreshed ID token, ignoring the
configured userIdentifierClaim. Keycloak users without an email claim
(using sub or another identifier) were kicked out on refresh even
though their initial login worked.
The callback path (auth_flow.go:226-239) already honored
userIdentifierClaim with "sub" fallback; PR #100 (commit a316a98)
added that support but missed the refresh path.
Mirror the callback logic in refreshToken so both paths behave the same.
Cleanup: rename Get/SetEmail to Get/SetUserIdentifier on SessionData
to match the actual semantics. The slot already stored the configured
identifier (email, sub, oid, upn, preferred_username), only the API
name was misleading. Storage key "email" → "user_identifier" and
combinedSessionPayload field E (json:"e") → Ui (json:"ui").
Compat note: existing user sessions invalidate on upgrade — every active
user re-authenticates once after deploying this change.
minor-release
Behaviour changes (potentially breaking for operators relying on the prior
unauthenticated SSE bypass):
* SSE (`Accept: text/event-stream`) and WebSocket upgrade requests now
return 401 when no authenticated session is present. Previously the
bypass forwarded unconditionally, which let any caller reach the
backend by setting the right header. Excluded URLs are unchanged.
Operators relying on unauthenticated SSE/WS access must move the path
into ExcludedURLs.
Performance fixes (target: long-running dashboards like Grafana / ArgoCD
where many panels poll concurrently while the page stays open):
* Stop honouring isTestMode() for the singleton-token-cleanup interval
under yaegi (the Traefik plugin runtime). In production the plugin was
running a 20 Hz no-op cleanup ticker because runtime.Compiler ==
"yaegi" tripped the test-mode branch.
* processAuthorizedRequest now resolves ID-token claims at most once per
request via SessionData.GetIDTokenClaims (already cached on the
session) and reuses them for both groups/roles extraction and
header-template rendering. Previously every authenticated request
parsed the JWT twice.
* Added extractGroupsAndRolesFromClaims to drive groups/roles off
pre-parsed claims; extractGroupsAndRoles still works for tests.
* Removed the unconditional session.MarkDirty() in the header-templates
branch. Templates only mutate request headers, not session state, so
the prior MarkDirty was re-encrypting and rewriting all session
cookies on every authenticated request that used header templates.
Other:
* Added isWebSocketUpgrade (RFC 6455 handshake detection — Connection:
Upgrade + Upgrade: websocket, tolerant of multi-token Connection
headers and case).
* Renamed applySSEUserHeaders -> applyBypassUserHeaders; it now returns
bool so the dispatcher can reject unauthenticated SSE/WS with 401.
* Added tests for SSE and WS bypass covering both the auth-rejection
path and the authenticated forward path.
* 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 9f96d8c already collapses
concurrent refresh-token grants on a single Traefik replica. With the
plugin's existing Redis (Dragonfly) cache infrastructure available, we
can extend that dedup across replicas: if pod A refreshes a token at
T+0 and pod B receives a request for the same session at T+1, pod B
should reuse pod A's result rather than POSTing the now-rotated refresh
token to the IdP.
Implementation:
- Add a refreshResultCache to UniversalCacheManager (memory-only when
Redis is disabled, Redis-backed in production via the existing
hybrid/Redis-only mode selection)
- Expose it through CacheManager.GetSharedRefreshResultCache and on the
TraefikOidc struct as refreshResultCache (CacheInterface)
- Inside the closure passed to RefreshCoordinator.CoordinateRefresh,
consult the cache first; on hit return immediately, on miss exchange
with the IdP and populate the cache for peers
- 5s TTL: long enough for siblings to observe, short enough that a
rotated refresh token cannot be re-supplied after the IdP has moved on
- Errors are intentionally NOT cached - peers must always be able to
retry on their own
Pragmatic choice: optimistic cache rather than a hard distributed lock.
- A hard lock (SET NX + poll) doubles Redis RTT and risks dead-locks
if a Traefik pod dies mid-grant.
- The user's BGP+Local externalTrafficPolicy already pins ingress for
a session to one node in steady state, so cross-pod racing is rare.
- This optimistic path catches the rare failover case without adding
failure modes.
Tests:
- TestCoordinatedTokenRefresh_CrossReplicaCacheHit: pre-populated cache
short-circuits the upstream call entirely (0 IdP calls)
- TestCoordinatedTokenRefresh_PopulatesCrossReplicaCache: leader stores
a successful result for peers to find
- TestCoordinatedTokenRefresh_ErrorIsNotCached: invalid_grant must not
poison the dedup cache - peers must retry independently
Hot-path JWT verification rebuilt the public key on every call:
jwk -> ToRSAPublicKey -> x509.MarshalPKIXPublicKey -> pem.Encode
-> verifySignature -> pem.Decode -> x509.ParsePKIXPublicKey -> verify
Under yaegi this pinned a CPU when many concurrent dashboard panels
poll behind the middleware. The PEM round trip is pure waste.
* jwk.go: cache pre-parsed crypto.PublicKey per kid alongside the
raw JWKSet (parallel cache entry, same 1h TTL, invalidates together).
* jwt.go: split verifySignatureWithKey from verifySignature; existing
PEM-input entry point preserved for backchannel-logout callers.
* token_manager.go: VerifyJWTSignatureAndClaims now goes straight from
jwks cache to verifySignatureWithKey, no PEM round trip and no
per-request availableKids slice.
* universal_cache.go: token/JWK/session Get() takes RLock when the
entry is unexpired, so concurrent token verifications no longer
serialize on a single mutex. LRU semantics for general and metadata
caches are unchanged (tests cover the strict-LRU contract there).
* mocks: MockJWKCache, EnhancedMockJWKCache, mockJWKCacheForLogout,
staticJWKCache satisfy the extended interface.
* Add debug logging around callback URL matching in ServeHTTP
The callback URL comparison at the core of OIDC flow had zero logging,
making it extremely difficult to diagnose redirect loop issues caused
by misconfigured callbackURL (e.g., full URL vs path-only).
Every other path comparison in ServeHTTP already logs debug info
(logout, backchannel, frontchannel, excluded URLs), but the callback
URL check was completely silent.
Added debug logs that show:
- The values being compared (request path vs configured callback)
- Whether the match succeeded or failed
- Configured redirURLPath during initialization
This would have immediately revealed the root cause of issue #1
where callbackURL was set as a full URL but compared against
req.URL.Path which only contains the path component.
Closes#3
* improve-callback-url-logging: Add init-time logging for callbackURL config
Move mutex unlock before calling Save() to prevent potential deadlock
when Save() method needs to acquire the same mutex.

* Fix cache serialisation
* fix(cache): add integer overflow protection for serialization
- [x] Add maxCacheEntrySize constant (64 MiB) to prevent memory overflow
- [x] Validate byte slice size before adding marker byte
- [x] Validate JSON-serialized data size before marker addition
- [x] Add comprehensive overflow protection test cases
* docs: add security fix documentation for integer overflow protection
* test: fix goroutine tests to use mock OIDC servers
The TestContextAwareGoroutineManagement tests were making real HTTP
calls to hardcoded URLs like https://example.com, causing failures
in CI when those requests timeout or return HTTP errors.
Changes:
- Added createMockOIDCServer() helper function using httptest
- Updated GoroutineCleanupOnContextCancel to use mock server
- Updated NoGoroutineLeakOnMultipleInstances to use 3 mock servers
- Updated SingletonTasksAcrossInstances to use mock servers array
This prevents network calls and makes tests more reliable and faster.
Fixes test failures in GitHub Actions CI.
* LRU + cache conflicts prevention.
* Bugfix universalCache flooding ( issue #105 )
1. Traefik cancels the context for old plugin instances
2. Each plugin's Close() method is called
3. The CacheInterfaceWrapper.Close() was calling cache.Close() on the shared singleton caches
4. Each Close() triggered Clear() which logged "Cleared all items" at INFO level
* Smarter approach to the cookies
- Single maxCookieSize = 1400 constant with clear documentation
- Combined cookie storage for ~40-45% size reduction
- Backward compatible migration from legacy cookies
* Tuneup the code.
* Allow to use multiple realms
This change is a ressurection of PR #88 which can't be merged due to significant refactor of the codebase.
* Fix the autocleanup routine to handle multiple realms correctly, update tests.
* Metadata rediscovery when provider is unavailable for any reason during the start.
This one prevents the permanent 503 from the plugin when OIDC provider was for some reason unavailable during the start.
* Allow internal IPs for OIDC configuration via extra flag.
Addresses issue #97
* Allow for internal IPs in OIDC configuration.
Addresses issue #97.
* feat: Add allowPrivateIPAddresses config option for internal networks
Adds a new configuration option `allowPrivateIPAddresses` that allows
OIDC provider URLs to use private IP addresses (10.x.x.x, 172.16-31.x.x,
192.168.x.x). This is useful for internal deployments where Keycloak or
other OIDC providers run on private networks without DNS resolution.
Security considerations:
- Loopback addresses (127.0.0.1, localhost, ::1) remain blocked
- Link-local addresses (169.254.x.x) remain blocked
- Default is false (secure by default)
Fixes#97
* feat: Support non-email user identifiers for Azure AD
Add userIdentifierClaim configuration option to support Azure AD users
without email addresses. This allows using alternative JWT claims like
"sub", "oid", "upn", or "preferred_username" for user identification.
- Default behavior uses "email" claim (backward compatible)
- Falls back to "sub" claim if configured claim is missing
- allowedUsers matches against the configured claim value
- allowedUserDomains only applies when using email-based identification
Fixes#95
* Race condition on traefik pod startup
When the plugin initializes and calls GetMetadataWithRecovery():
1. Checks cache first (if metadata is cached, returns immediately)
2. Creates a retry executor with startup-optimized settings (10 attempts, 1s delays)
3. Attempts to fetch metadata from the OIDC provider
4. If the fetch fails with a retryable error (connection refused, EOF, TLS/certificate errors, Traefik default cert), it waits and retries
5. After 10 attempts or on a non-retryable error, returns the error
This allows the plugin to handle the race condition where:
- Traefik initializes the plugin before routes are established
- Traefik serves its default certificate before loading real ones
- The OIDC provider pod isn't fully ready yet
Fixes issue #90
* Race condition on traefik pod startup

Fixes issue #90
* Headers too big and 431 responses
Added new option `minimalHeaders` to reduce the size of forwarded headers from the auth middleware to backend services.
- When minimalHeaders: false (default): All headers are forwarded as before
- X-Forwarded-User (always set)
- X-Auth-Request-Redirect
- X-Auth-Request-User
- X-Auth-Request-Token (the large ID token)
- X-User-Groups, X-User-Roles (if configured)
- When minimalHeaders: true: Reduces header overhead
- X-Forwarded-User (always set)
- X-User-Groups, X-User-Roles (still forwarded if configured)
- Custom templated headers (still processed)
- Skipped: X-Auth-Request-Token, X-Auth-Request-User, X-Auth-Request-Redirect
Fixes issues #64 and #86
* Size computation for allocation may overflow
Performing calculations involving the size of potentially large strings or slices can result in an overflow (for signed integer types) or a wraparound (for unsigned types). An overflow causes the result of the calculation to become negative, while a wraparound results in a small (positive) number.
When introspection explicitly returns that a token is inactive/revoked/expired, the plugin now properly triggers re-authentication or refresh instead of falling back to ID token validation. This fixes the functional issue where users
weren't being redirected to re-authenticate.
Redis change ensures that when the caller's context is cancelled (e.g., the 200ms timeout in UniversalCache.Get()), the operation aborts quickly instead of continuing with retries.

* Automatic discovery of the scopes.
Issue #61 raised very valid concerns about users configuring scopes that are not supported by the provider.
This change introduces automatic discovery of supported scopes by fetching the provider's discovery document and filtering out unsupported scopes.
Before:
User configures: scopes: ["openid", "profile", "email", "offline_access"]
Self-hosted GitLab: "The requested scope is invalid, unknown, or malformed"
Authentication: ❌ FAILS
After:
User configures: scopes: ["openid", "profile", "email", "offline_access"]
Middleware checks discovery doc → offline_access not supported
Automatically filters to: ["openid", "profile", "email"]
Authentication: ✅ SUCCEEDS

* Issue #53: Fix CSRF token handling in reverse proxy
1. ✅ HTTPS Detection Fixed (session.go:723)
- Now uses X-Forwarded-Proto header instead of r.URL.Scheme
- Properly detects HTTPS in reverse proxy environments
2. ✅ SameSite Cookie Attribute Fixed
- Removed automatic SameSiteStrictMode for HTTPS (would break OAuth)
- Keeps SameSiteLaxMode to allow OAuth callbacks from external domains
- Only uses Strict for AJAX requests which don't involve OAuth redirects
3. ✅ Cookie Domain Handling Fixed
- Now respects X-Forwarded-Host header for cookie domain
- Ensures cookies are set for the public domain, not internal proxy domain
4. ✅ EnhanceSessionSecurity Properly Integrated
- Function is now actually called during session save
- Applies security enhancements without breaking OAuth flow
Why Issue #53 Failed Before:
1. Cookies were not marked Secure in HTTPS environments (browser wouldn't send them back)
2. If they had been Secure with SameSite=Strict, Azure callbacks would still fail
3. Cookie domain might have been wrong (internal vs public domain)
Why It Works Now:
1. Cookies are properly marked Secure for HTTPS
2. Uses SameSite=Lax to allow OAuth provider callbacks
3. Cookie domain uses public domain from X-Forwarded-Host
4. CSRF token persists through the entire OAuth flow
* Next set of enhancements together with memory usage improvements.
