feat(server): authenticated remote dashboard listener with cookie sessions#2414x3M3x wants to merge 1 commit into
Conversation
📝 WalkthroughWalkthroughThe change adds an optional authenticated dashboard listener with restricted routes, listener-specific management policies, cookie-based GUI sessions, port validation, lifecycle handling, client integration, documentation, and tests. ChangesRemote dashboard access
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to This change adds authenticated remote dashboard access with cookie sessions and listener-specific management behavior. An aborted initial management request may remain pending until the session-probe timeout, which can delay or waste a dashboard request; the risk is bounded, so the PR is mergeable with owner awareness and follow-up.

…sions A dedicated dashboardListener binds a second socket (typically a tailnet address) that serves only the web app, /opencodex-session and /api/*, and refuses the entire /v1 data plane, /healthz and /readyz before any handler runs. The main proxy listener is untouched, so Codex keeps its existing provider and auth mode. POST /api/auth/session exchanges the admin token for a 12h HttpOnly SameSite=Strict cookie; GET reports the session CSRF material so a page refresh re-arms in-memory headers without re-prompting. Cookie sessions authenticate all management routes: reads bind to the Host-derived origin, mutations additionally require the per-session CSRF token and Origin. The dashboard web app arms these headers from the cookie probe and mints the cookie after a manual admin-token sign-in.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Both pages claim the dashboard listener serves /opencodex-session; that depends on an unverified loopback check. The route allowlist admits the path, but src/server/index.ts line 1598 serves the bootstrap only when issueGuiSession(req, config, managementAuth) at line 1593 returns a session, and it is called with the shared loopback config rather than dashboardPolicy(). If issueGuiSession refuses non-loopback requests, the dashboard listener never serves that path and both sentences overstate the surface. If it does not refuse, the served page would carry a session token for a remote visitor, which is the security question raised on src/server/index.ts lines 865-881.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Correct the "every listener" claim; the unauthenticated loopback listener refuses these endpoints.
Line 143 states that the session endpoints exist on every listener. That contradicts line 102 of this same document, which states that the unauthenticatedLoopbackListener returns 404 for everything except the four /v1 routes, "including /api/* and the dashboard."
The code agrees with line 102. loopbackRouteAllowed in src/server/index.ts lines 668-683 admits only /v1/responses, /v1/responses/compact, /v1/models, /v1/realtime, and /v1/live. A request to /api/auth/session on that listener is rejected at line 858 before handleGuiSessionEndpoint can run at line 1012.
A reader who enables both listeners would follow line 143 and receive a 404.
Restrict the claim to the proxy listener and the dashboard listener.

Add a case that pins the WebSocket refusal on the dashboard listener.
dashboardRouteAllowed refuses WebSocket upgrades at src/server/index.ts line 699. That branch is one of the three headline refusals in this PR, and no test exercises it.
The current loop only sends plain GET requests. A future edit that moves the path.startsWith("/api/") allow above or below the upgrade check would not fail any test.

Tighten the CSRF assertion so a 403 regression cannot pass.
Line 164 asserts only not.toBe(401). The PR objectives state that management origin validation previously returned 403 for non-loopback dashboard requests, and that management-api.ts now uses the receiving listener's policy to fix it.
handleManagementAPI returns 403 with "cross-origin request blocked" when isAllowedManagementOrigin fails. If that regression returned, this test would still pass, because 403 is not 401.
Assert that the status is neither 401 nor 403. That keeps the assertion tolerant of body-validation statuses while pinning both admission gates.
