Migrate auth to httpOnly cookies + CSRF, with bearer-token fallback - #954
Migrate auth to httpOnly cookies + CSRF, with bearer-token fallback#954Doezer wants to merge 7 commits into
Conversation
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.

The client centralizes authenticated requests through ChangesAuthentication and security
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to 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.

📊 Automated PR Analysis
SummaryThis PR migrates authentication from localStorage-stored JWTs to httpOnly cookies with double-submit CSRF protection, while retaining Authorization: Bearer support for non-browser clients and an in-memory fallback for already-logged-in tabs. It adds server-side CSRF middleware, cookie helpers, a logout endpoint, and updates numerous client pages that bypassed the shared fetch wrapper. Review Checklist

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].

Keep legacy-token migration out of render.
When AuthProvider runs under React Strict Mode, capture the token in a pure initializer and perform an idempotent post-commit migration. Gate /api/auth/me until migration completes, and add StrictMode regression coverage.

Strict Mode’s double-render behavior.
- 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.

…review - 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.

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
