Description

Part of a split of #935 into smaller, independently reviewable PRs (see that PR for the full list). This is item 8, the highest-risk change of the eight — please review carefully.

Stacked dependency: this branch is built on top of #953 (default-deny auth boundary, item 1 — CSRF is mounted right after that boundary) and #952 (log level + secret redaction, item 6 — creates server/security.ts which this PR extends with CSRF). The diff below/GitHub's file list will include their changes until those two merge; once they do, this branch should be rebased onto main and the diff will shrink to just this item. Please land #953 and #952 first.

The JWT was issued in the login response and stored in localStorage — readable by any injected script. Now set as an httpOnly cookie with a double-submit CSRF token; Authorization: Bearer still works unchanged for any non-browser client and is exempted from CSRF (not cookie-exposed). Existing logged-in users are migrated gracefully rather than stranded.

  • server/security.ts: setAuthCookies/clearAuthCookies (httpOnly JWT cookie + a readable, non-httpOnly CSRF cookie holding an independently-generated crypto.randomBytes(32) token — deliberately not reusing the session JWT, since that would let any script read it out of document.cookie and replay it as a bearer token) and csrfProtection, a double-submit CSRF middleware for non-safe methods on cookie-authenticated requests (X-CSRF-Token header must match the CSRF cookie, with a same-host Origin/Referer fallback). Bearer-authenticated requests skip CSRF entirely.
  • server/auth.ts: getRequestToken() now accepts either the Authorization: Bearer header or the httpOnly auth cookie (bearer takes priority), parsing the Authorization scheme explicitly so a non-Bearer scheme falls through to the cookie check instead of misreporting 403. authenticateToken/optionalAuthenticateToken tag req.authSource (cookie | bearer) so csrfProtection can key off it.
  • server/routes.ts: mounts csrfProtection right after the default-deny auth boundary. Login and setup call setAuthCookies in addition to returning the token in the response body (backward compatibility for bearer-only clients). Adds POST /api/auth/logout (auth-protected) to clear the cookies server-side.
  • Client: apiFetch stops reading/writing a JWT in localStorage, relies on credentials: 'include' for the cookie, and attaches X-CSRF-Token from the readable CSRF cookie on non-GET requests. A small in-memory-only bearer token bridges a browser tab that was already logged in via the old localStorage flow; auth.tsx migrates any pre-existing token into memory and scrubs localStorage on mount. logout() now awaits the server-side call and only clears local state on success, so a network failure doesn't silently "restore" a still-live session.
  • Fixed several pages (downloads.tsx, indexers.tsx, downloaders.tsx, AddGameModal.tsx, xrel-releases.tsx, settings.tsx) that bypassed apiFetch with raw fetch() calls manually reading the localStorage token (two were sending Bearer null) — these would have silently broken once localStorage stopped being written.

Please double-check

  • The CSRF cookie's secure flag only trusts X-Forwarded-Proto when trust proxy is actually enabled (production).
  • POST /api/auth/login and /api/auth/setup still return token in the JSON body (in addition to setting cookies) for bearer-client backward compatibility — flag if you'd rather cut over fully.
  • An already-logged-in user's session is kept alive in-memory for the current tab via their old bearer token, but isn't persisted — closing the tab means logging in again next time (no bearer→cookie exchange endpoint was added).

Validation

  • npm run check — passes
  • npx eslint on changed files — passes
  • npx vitest run server/__tests__/ (full server suite) — 1540 passed, 6 skipped, 0 failed
  • npx vitest run client/ (full client suite) — 623 passed, 1 skipped, 0 failed

Type of change

  • Bug fix (non-breaking change which fixes an issue)
  • Security-relevant change — moves the session token out of localStorage (XSS-readable) into an httpOnly cookie with CSRF protection.

JWTs were issued in the login/setup response body and stored in
localStorage, then sent as Authorization: Bearer on every request --
readable by any injected script (XSS token theft).

server/security.ts: add setAuthCookies/clearAuthCookies (httpOnly JWT
cookie + a readable, non-httpOnly CSRF cookie whose value doubles as
the CSRF token; SameSite=Lax, Secure when the request is over TLS)
and csrfProtection, a double-submit CSRF middleware for non-safe
methods on cookie-authenticated requests (X-CSRF-Token header must
match the CSRF cookie, with a same-host Origin/Referer fallback).
Bearer-authenticated requests skip CSRF entirely -- browsers don't
auto-attach bearer tokens cross-site, so they aren't exposed to it.

server/auth.ts: getRequestToken() now accepts EITHER the
Authorization: Bearer header or the httpOnly auth cookie (bearer
takes priority when both are present), and authenticateToken/
optionalAuthenticateToken tag req.authSource (cookie | bearer) so
csrfProtection can key off it. Added to the Request augmentation in
server/types.ts.

server/routes.ts: mount csrfProtection right after the default-deny
auth boundary (item 1). Login and setup now call setAuthCookies in
addition to returning the token in the response body -- keeping the
body for backward compatibility with non-browser/bearer-only clients,
documented at both call sites. Added POST /api/auth/logout
(authenticateToken-protected) to clear the cookies server-side, since
an httpOnly cookie can't be cleared by client JS.

Client: apiFetch (client/src/lib/queryClient.ts) stops reading/writing
a JWT in localStorage, relies on credentials: 'include' for the
cookie, and attaches X-CSRF-Token from the readable CSRF cookie on
non-GET requests. A small in-memory-only bearer token
(setBearerToken) exists solely to bridge a browser tab that was
already logged in via the old localStorage flow: auth.tsx migrates
any pre-existing localStorage token into this in-memory value and
scrubs localStorage immediately on AuthProvider mount, so an
already-logged-in user isn't stranded, without ever persisting a
token again. The /api/auth/me check now always runs (a valid session
may exist purely via the cookie). logout() best-effort calls the new
POST /api/auth/logout endpoint.

Also fixed several pages (downloads.tsx, indexers.tsx, downloaders.tsx,
AddGameModal.tsx, xrel-releases.tsx, settings.tsx) that bypassed
apiFetch with raw fetch() calls manually reading the localStorage
token (in a couple of cases literally sending 'Bearer null' when no
token was set) -- these would have silently broken once localStorage
stopped being written. They now route through apiFetch/apiRequest,
picking up cookie auth, CSRF headers, and basePath handling for free.

Tests: server/__tests__/cookie-auth-csrf.test.ts (new, unmocked
auth.js/security.js like auth-boundary.test.ts) covers cookies set on
login/setup, cookie-only auth success, CSRF rejection on missing/
mismatched header, CSRF success on matching header, the Origin/Referer
fallback (both directions), bearer auth working end-to-end and
skipping CSRF, and cookie clearing on logout. Updated
client/src/lib/__tests__/queryClient.test.ts, client/__tests__/
queryClient.test.ts, client/src/__tests__/auth-provider.test.tsx, and
client/__tests__/auth.test.tsx for the new in-memory-bearer-token
model and CSRF header attachment.
…, awaited logout, scheme parsing, trusted-proxy secure flag

- CSRF cookie no longer reuses the session JWT: generate an independent
  crypto.randomBytes(32) token instead, closing the token-exfiltration/
  CSRF-bypass path where any page script could read the JWT out of
  document.cookie and replay it as a bearer token.
- Client logout now awaits the server-side logout call and only clears
  local session state on success, showing an error toast and leaving the
  session alone on failure so a live httpOnly cookie session doesn't get
  silently 'restored' after an apparent logout.
- getRequestToken now parses the Authorization scheme explicitly and only
  treats 'Bearer <token>' as a bearer token, falling through to the cookie
  check for any other scheme instead of misreporting 403.
- cookieOptions' secure flag: only trust X-Forwarded-Proto when trust proxy
  is actually enabled (production); avoids trusting that header from an
  unconfigured/untrusted hop in non-production topologies.
- auth.tsx: explicitly destructure the lazy-initializer-only useState call
  into unused, underscore-prefixed bindings instead of an undestructured call.

📝 Walkthrough

Walkthrough

The PR adds HTTP-only cookie authentication with CSRF protection and legacy-token migration. The client centralizes authenticated requests through apiFetch. The server supports cookie and Bearer credentials, soft logout, cookie cleanup, and secret redaction.

Changes

Authentication and security

Layer / File(s) Summary
Security helpers and redaction
server/security.ts, server/__tests__/security-redaction.test.ts
Adds authentication-cookie helpers, CSRF validation, and recursive secret redaction for structured values.
Server authentication boundary and cookie routes
server/auth.ts, server/routes.ts, server/types.ts, server/__tests__/auth.test.ts, server/__tests__/cookie-auth-csrf.test.ts
Supports Bearer and cookie authentication, records req.authSource, protects API routes, sets cookies during login and setup, and clears cookies during logout.
Client session state and request transport
client/src/lib/auth.tsx, client/src/lib/queryClient.ts, client/src/lib/__tests__/*, client/__tests__/*
Migrates legacy tokens into memory, checks cookie-only sessions, clears bearer state after unauthorized responses, adds credentials and CSRF headers, and updates authentication tests.
Authenticated request migration
client/src/components/AddGameModal.tsx, client/src/pages/auth/setup.tsx, client/src/pages/downloaders.tsx, client/src/pages/downloads.tsx, client/src/pages/indexers.tsx, client/src/pages/settings.tsx, client/src/pages/xrel-releases.tsx
Removes page-level localStorage token handling and routes authenticated requests through apiFetch. Setup relies on the server-set cookie.
Estimated code review effort
server/security.ts, server/routes.ts, server/auth.ts, client/src/lib/auth.tsx, client/src/lib/queryClient.ts
The change spans client and server authentication flows, CSRF enforcement, logout state handling, request migration, and extensive tests.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 497ef

The migration can let a stale or invalid bearer token override a valid cookie session, causing account mix-ups or denied access, while the migration path may also lose an existing user's session. Invalid dates can additionally break secret redaction, and early authentication failures can leave setup or configuration screens stuck loading. These correctness and availability issues should be fixed before merge.

React Strict Mode useState initializer called twice development official documentation

💡 Result:

In React Strict Mode, the useState initializer function is intentionally called twice during development [1][2]. This is a development-only behavior designed to help you identify and fix accidental impurities or side effects in your code [1][2]. Key details include: * Purpose: Because React expects component functions, state initializers, and updater functions to be pure, calling them twice helps surface bugs caused by side effects [1][2]. If a function is pure, invoking it multiple times does not alter the result or the application state [1][2]. * Mechanism: React uses the result of one of the calls and ignores the result of the other [1][3]. This behavior does not occur in production builds [1][4]. * Scope: This double-invocation applies to functions passed to useState, useReducer, and useMemo, as well as the component function body itself (excluding event handlers) [2][4]. If your initializer function is pure, this process should not affect your logic or cause issues [1][2]. If you notice unexpected behavior, it is likely an indicator that your initializer contains side effects (such as mutating external data or performing non-idempotent operations) that should be removed to ensure consistent behavior in production [1][2][4].

- Fix logout not clearing cookies when the auth cookie is expired/
  invalid: the default-deny /api boundary previously hard-rejected
  those requests with authenticateToken before the logout handler ever
  ran, leaving stale questarr_auth/questarr_csrf cookies in the
  browser. Added a SOFT_AUTH_API_ROUTES allowlist so the boundary runs
  optionalAuthenticateToken for /auth/logout instead -- the request
  always reaches the handler, while req.authSource is still populated
  (and csrfProtection still enforced) for a valid cookie.
- Removed the now-redundant per-mount authenticateToken on
  /api/imports, /api/import-tasks, and /api/system: the default-deny
  boundary already authenticates every non-public /api route before
  these mounts are reached, so the second pass was a duplicate
  jwt.verify + storage.getUser on every request with no added
  protection.
- Fix redactSecrets silently collapsing Date/Buffer/Map/Set values to
  {} (Object.entries returns [] for these) -- now preserves them as an
  ISO string, a byte-count summary, and recursively-redacted
  object/array forms respectively. This runs on every structured log
  line via pino's formatters.log hook, so timestamps and similar
  fields were losing their value in all logs.
- Extracted AuthProviderProps interface instead of an inline props
  type, per the repo's coding guidelines.
- Added regression coverage for all three fixes.

Declined: migrateLegacyLocalStorageToken StrictMode idempotency
(auth.tsx) -- same reasoning as the original decision in 91a6121:
React.StrictMode isn't used anywhere in this codebase, so the
double-invocation scenario isn't reachable, and forcing idempotency
would fight the function's documented intentional per-mount
bearer-token reset behavior.

Addressed 4 of CodeRabbit's 5 findings in ee5cf8c:

  • Logout doesn't clear cookies with an expired/invalid auth cookie — real bug, and worse than the report suggested: swapping the route's own authenticateTokenoptionalAuthenticateToken alone wouldn't have fixed it, since the default-deny /api boundary (requireAuthenticationForApi, mounted before any route) already hard-rejects with authenticateToken before the route handler is ever reached. Added a SOFT_AUTH_API_ROUTES allowlist so the boundary runs optionalAuthenticateToken for /auth/logout specifically — the request always reaches the handler and clears the cookies, while req.authSource still gets set for a valid cookie so csrfProtection keeps enforcing the CSRF check for that case. Added a regression test with an invalid questarr_auth cookie asserting 200 + both cookies cleared.
  • Redundant authenticateToken on /api/imports, /api/import-tasks, /api/system — confirmed genuinely redundant (the default-deny boundary already authenticates every non-public /api route before these mounts run) and removed rather than documented, since there was no actual defense-in-depth benefit — just a second jwt.verify + storage.getUser on every request. Existing route test suites for all three routers still pass.
  • redactSecrets collapses Date/Buffer/Map/Set to {} — real bug (Object.entries on these returns []), and it runs on every structured log line via pino's formatters.log hook, so this was live in production logs. Added explicit handling: ISO string for Date, byte-count summary for Buffer, recursive redaction through Object.fromEntries/Array.from for Map/Set. Added regression tests for all four.
  • AuthProviderProps interface — done, per the repo's coding guideline of named prop interfaces over inline types.

Declining one:

  • migrateLegacyLocalStorageToken StrictMode idempotency — same reasoning as the original decision on this exact finding (commit 91a6121): React.StrictMode isn't used anywhere in this codebase, so the double-invocation scenario the finding describes isn't reachable, and forcing idempotency would fight the function's documented intentional per-mount bearer-token reset behavior. Leaving that thread open rather than resolving.

Merged main in (497ef24) to resolve the conflict left by #953's merge — this branch was stacked on it. Also picks up the unrelated changes now on main from #950/#952 merging (IGDB canonicalization, log-level fix). npm run check, full server suite (1555 passing), and full client suite (630 passing) all green after the merge; lint clean.

Authorization: Bearer takes precedence over the auth cookie. Therefore, an invalid bearer can reject a valid cookie session, and a valid bearer can select the wrong user. Add tests for both mixed-credential cases.

94-107: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Do not clear the entire QueryClient from the /api/auth/me unauthorized branch.

When /api/auth/me returns 401 or 403 before /api/auth/status settles, queryClient.clear() cancels the shared status query and removes its cache while its observers remain attached. This can leave setup routing and configuration stuck loading. Clear only authentication state, and add a regression test for this response order.

Comment thread server/security.ts Outdated
new Date("garbage").toISOString() throws RangeError instead of
returning a value, so an invalid Date reaching redactSecrets (e.g. a
malformed timestamp logged from untrusted input) would crash the
formatters.log hook instead of producing a safe log line. Returns a
sentinel string for invalid dates instead. Added a regression test.

Addressed the one new finding from the post-merge review pass in f69df8b: redactSecrets threw RangeError on an invalid Date (new Date("garbage").toISOString() throws rather than returning a value) — a malformed timestamp reaching the logger would have crashed pino's formatters.log hook instead of producing a safe log line. Now returns "[Invalid Date]" for that case. Added a regression test.

All other findings in this pass were already fixed in earlier commits (confirmed by CodeRabbit's own "✅ Addressed in commit..." notes) or are the previously-declined StrictMode migration finding, which stays declined for the same reason as before.

npm run check, security-redaction.test.ts (13 passing), and lint are all green.

@Doezer, I will review the current changes, with focus on authentication, cookie handling, CSRF protection, and logout behavior.

- Login now clears the in-memory migrated bearer token on success.
  Authorization takes priority over the auth cookie on every request
  server-side, so a stale/invalid bearer left over from a pre-cookie
  session would keep silently overriding a fresh, valid cookie login
  on every subsequent /api/auth/me check.
- The /api/auth/me 401/403 handler no longer wipes the entire
  QueryClient. queryClient.clear() could cancel the still-in-flight
  /api/auth/status query and strand its observers (setup/config
  screens) on an indefinite loading state; now removes every cached
  query except that one instead.
- Added regression tests for both.

Fixed both new findings from the last review pass in 1fd078e:

  • Stale migrated bearer overriding a fresh cookie login — real bug, and more severe than the label suggested: Authorization takes priority over the auth cookie on every request server-side, so a user with an invalid/stale bearer left over from the pre-cookie migration would keep getting silently rejected on /api/auth/me forever, even after a fully successful, valid login sets a fresh cookie. Fixed by clearing the in-memory bearer token in login()'s onSuccess. Skipped the suggested "retry once without it" addition — clearing on login closes the actual defect (a permanently-blocked session) without adding retry machinery for a case that no longer arises once the bearer is cleared.
  • **queryClient.clear() wiping the whole cache, including the concurrently-running /api/auth/status query, on a /api/auth/me 401/403** — confirmed: this could cancel that query's in-flight fetch and strand setup/config screens on indefinite loading. Now removes every cached query except /api/auth/status` instead.

Added regression tests for both. Full client suite (632 passing), npm run check, and lint all green.
