…issions The authenticated /api/v1 group only checked login and MFA. Admin handlers (users, API tokens, settings, sessions, audit logs) never checked roles, so any logged-in user or API token, including the CircleCI token, could create admins, mint convox:*:* tokens, or turn off deploy approvals and MFA. The checks were lost in the gin rewrite. - New Authorize middleware runs after Authenticated. It enforces the access policy declared for every route in rbac's route table and denies routes without a policy. Admin routes require their gateway permission. Self-service routes (own MFA, /info, settings reads) are open to any logged-in human. - API tokens are allowed only on the routes the CLI uses in CI: /info, /rack, creating a deploy approval request and reading one by ID. Tokens can no longer approve deploys or call any admin endpoint. - rbac.Manager.Authorize(principal, permission) replaces Enforce, EnforceUser and EnforceForAPIToken. Humans are checked against the roles on their current DB record, so demotion and deletion apply on the next request instead of after a restart (Casbin user groupings were only ever added, never removed). API tokens need the permission themselves AND their owner's current role must allow it. Suspended or locked users and their tokens are denied. - Handler and proxy checks (env reads/writes, secret masking, deploy approval view/create, Slack) now authorize the real caller. Before, an admin-owned token was treated as the admin. - Audit logs get their own gateway:audit_log:read permission instead of borrowing deploy_approval_request:read. Listing approval requests and their audit logs requires approver permission, matching the handlers. Admin role gains security:*:*, which the rack TLS cert refresh route requires. - Tokens of locked owners are rejected at authentication. Token creation honours expires_at, which the CLI already sends but the server ignored. Creating a token for an unknown user returns 404 instead of dereferencing nil. - Removed dead code: RequireRole, Authenticated's unused rbac parameter, and the header-based env permission check that nothing called (the proxy already strips Env headers). routes/authorization_test.go exercises the real router as viewer and deployer sessions, a viewer token, the production-style admin-owned cicd token and an admin-owned wildcard token, and asserts every admin endpoint refuses them.
A session that had only passed Google login could call the MFA enrollment endpoints (MFANone), enroll its own TOTP and be marked MFA-verified, then delete the user's real factors and mint tokens. TOTP enrollment also replaced the user's backup codes and returned fresh ones, so an attacker didn't even need to enroll. - New RequireVerifiedMFASession middleware: a session whose user must complete an MFA challenge can only reach mfa/status, mfa/verify, the WebAuthn assertion endpoints and /info until it verifies. It may also complete the challenge inline with an MFA header (used by the SPA step-up dialog). - The same rule applies on /rack-proxy, so a pending web session token can't be replayed as a Bearer credential. - Adding a factor when already enrolled requires a recent step-up; first-time enrollment is unchanged. - Enrollment no longer replaces an enrolled user's backup codes (regeneration stays a separate step-up action). - MFA factor enrollment (incl. YubiOTP), deletion and backup-code regeneration now write DB audit events.
PUT /api/v1/apps/:app/env only validated the submitted key, then joined values with newlines for the rack API. A value like "x\nDATABASE_URL=postgres://evil" injected a second line that Convox applied (last duplicate wins). That bypassed protected env vars and the secrets:set permission, and the audit log only recorded the harmless key. MergeEnv now requires keys to match [A-Za-z_][A-Za-z0-9_]* and rejects CR, LF and NUL in values. The handler returns 400 with an explanation.
The proxy copied every client header to the rack except a five-entry denylist. The rack trusts several of those headers because the gateway authenticates as admin with the rack password: - Image/Volumes/Privileged on a process run let ops or an approved CI token start an arbitrary image with host paths mounted - X-Convox-Actor forged the rack's own audit trail - X-Convox-TID switched tenant namespace resolution - Client headers now pass through an explicit allowlist derived from the Convox SDK (sdk.Client.Headers, stdsdk.Client.Request) and the header tags on structs.LogsOptions, ProcessExecOptions, ProcessRunOptions and ObjectOptions. Credentials, cookies, actor and tenant overrides, X-Forwarded-*, hop-by-hop headers, Accept-Encoding, env headers and gateway-internal headers are dropped, on both HTTP and WebSocket requests. - Run options that escape the release image or scheduling constraints (Image, Volumes, Privileged, Node-Labels, Node-Affinity, Run-Tolerations, System-Critical, Run-Annotations, Run-Labels) need the new convox:process:run_privileged permission, which only the admin wildcard covers. API tokens can never use them. Requests without that permission get 403 and never reach the rack. - The gateway sets X-Convox-Actor to the user's email, or token:<name> for API tokens. - New StripInternalHeaders middleware runs first and removes client-supplied X-Audit-Resource, X-Release-Created, X-Original-Path, X-User-*, X-API-Token-*, X-Auth-Source, X-RBAC-Decision and X-Rack-* headers, which the audit logger and request logger read. - buildTargetURL escapes the authorized path, so %3F/%23 can't truncate the route the rack sees. Paths with control characters, '?', '#' or dot segments are rejected before route matching. - The WebSocket dial follows redirects only on the rack's own host, so the rack credential is never sent anywhere else.
…oduction Sentry was initialised with SendDefaultPII=true, so every 5xx event carried the Authorization header (session or API token plus inline MFA code) and session cookies. PII collection is now off, and a BeforeSend hook strips everything except a small header allowlist, plus cookies, query strings, request bodies and env. The gateway now refuses to start when its database is marked production while any test-only switch is set: DEV_MODE, E2E_TEST_MODE (skips WebAuthn assertion checks), AWS_ENDPOINT_URL_S3 or POSTMARK_API_BASE. GOOGLE_OAUTH_BASE_URL must be https there. Development and E2E databases are unaffected.
- ID tokens must have email_verified=true. - When GOOGLE_ALLOWED_DOMAIN is set, the hosted-domain (hd) claim must match it as well as the email domain (case-insensitive). Before, a bare suffix compare on the email was the only check. - The ID token verifier accepts RS256 only. Google never uses HS256, and allowing it only matters if the issuer can be swapped. - GOOGLE_ALLOWED_DOMAIN is required outside DEV_MODE. An empty value used to let any Google account sign in. - The mock OAuth server now emits hd like Google does for Workspace accounts.
- Listing deploy approval requests and reading a request's audit trail were mapped to deploy_approval_request:approve, which carries MFAAlways, so every page load demanded a fresh MFA code. They now use the read-level :list permission (admin-only); the handlers still require approver permission. A test asserts no GET route can require MFAAlways. - A 403 from the Authorize middleware names the missing permission, e.g. "insufficient permissions: requires convox:env:read". - E2E login helper: when login lands on the MFA challenge, complete it with a TOTP code like a user would. Enrolling TOTP directly in the DB for an already logged-in user now also marks that session MFA-verified, matching a real UI enrollment (step-up stays unset). - cli-login-webui clears TOTP replay state before generating its approve code, so another test on the same shard can't have used the time step already. - CLI E2E expectations updated for the new permission error message.

The redirect check only compared hosts, so a wss -> ws redirect on the rack host would resend the rack Basic credential in cleartext. The redirect must now keep both the host and the scheme of the configured rack URL.

…role Review fixes for PR #19: - Refuse query parameters the Convox SDK never sends. The rack reads options from the query string as well as headers and the body, so `?command=`, `?env=` and `?manifest=` could override the exec command, release env and build manifest the gateway had checked. The web UI's scale request now sends `count` in the form body, like the SDK. - deploy_with_approval no longer lets a token exceed its owner's current role. - Env change refusals name the keys and the reason ("ADMIN_PASSWORD is a protected env var for docspring. Unprotect it in rack-gateway settings to change it.") instead of "You don't have permission to create releases." Removing a secret now needs secret:set, like changing one. - Token names may not contain control characters (they become the X-Convox-Actor header). - The production guard also refuses AWS_ENDPOINT_URL and the STS/KMS endpoint overrides. Adds tests for token callers, the websocket header path and the query allowlist.
Sessions created while a user had no factor are marked MFA-verified at login. Once the user enrolls their first factor, those sessions must prove it too, so first enrollment clears their MFA state; the session that enrolled is re-verified. YubiKey enrollment now re-verifies its session like TOTP and WebAuthn do. Also adds tests that ID tokens are only accepted when signed with RS256 and that a locked owner's API tokens are rejected.
Review fixes for PR #19 (A03-F01, A03-F03): - The MFA challenge page and step-up dialog have a "Use a backup code" mode. Codes are accepted in any case, with spaces or dashes. Now that a pending session can't enroll a new factor, this is the recovery path for a user who has lost their authenticator. - Approving a CLI login with MFA also verifies the browser's web session for the same user, so the web UI doesn't ask for MFA again afterwards. - /api/v1/info reports mfa_pending, and the web UI sends a pending session to the challenge page instead of letting every request fail. - When several requests need step-up at once, the dialog now settles all of them (retry after verifying, reject on cancel) instead of leaving all but the last one hanging.
Review fixes for PR #19 (A01-F01, A01-F02, A06-F01, A06-F04, A06-F05). Locking admin routes down removed access the viewer, ops and deployer roles need. This restores it with ownership rules instead of admin-only routes: - Every user can view their own profile, sessions and audit trail and sign out their own sessions (route-table self rule on /users/:email: exact email match, people only, never API tokens). Other users' records still need gateway:user:read / user:update / audit_log:read. - The team directory (GET /users) needs the new gateway:user:list, which every role has. Lock and MFA details are only returned with user:read. - API tokens: gateway:api_token:read/create/update/delete cover the caller's own tokens; the new gateway:api_token:manage (admin) covers everyone's. Deployers can issue CI tokens for themselves. A token's permissions must be within its owner's current role at create and update time, as well as at request time. - /api/v1/info returns the caller's permissions so the web UI shows only what they can use; navigation and pages follow them. - Fixes the role editor, which called an unregistered route. - CLI: deploy-approval approve and test-auth handle API tokens clearly. - A test walks the real router: every /api/v1 route is public by design or has a policy, and every policy has a route. - Docs updated for the new permissions, token rules, self-service, the production safety check and the proxy header and query allowlists.
…alls .claude/ holds local agent worktrees (several GB), which made the CLI E2E deploy tarball exceed the gateway's 500MB manifest-check limit and would bloat any Docker build context. CLI commands in the E2E harness now get </dev/null so a command that reads stdin (env set) can't hang the run.

- The OTP, MFA and backup code inputs take focusOnMount instead of an autoFocus prop: they focus their first field from an effect and never used the native attribute. - Small cleanups DeepSource flagged: no redundant undefined arguments, the per-user audit log call uses the generated client, and the scale mutation is no longer async without an await. - Naming yourself as a token's owner is matched case-insensitively. - The redirect-after-login E2E spec enforces MFA for its user, so it no longer depends on global settings left by earlier tests in the worker.
