From b44fb1ad234501c42eb5e952b1127b6f7599b7ee Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?F=C3=A9lix=20Malfait?= Date: Thu, 30 Apr 2026 17:00:26 +0200 Subject: [PATCH] fix(security): reject ?token= URL query parameter for authentication (#20154) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Removes the `?token=` URL query-parameter fallback from JWT authentication. Every authenticated route (`/graphql`, `/metadata`, REST, etc.) used to accept a full workspace JWT in the URL alongside the `Authorization` header. The fallback was intended for the REST API Playground only, but it was wired into the global Passport JWT extractor and applied to every route. URL-borne tokens leak into: - Server access logs (nginx / Apache / CDN / proxy / load balancer) - Log aggregators (Datadog, CloudWatch, Loki, Sumo, …) - Browser history (and synced across devices) - `Referer` headers when navigating to external pages - Browser extensions with `tabs`/`webNavigation` permissions A leaked log line was equivalent to a leaked workspace credential for the lifetime of the token. ## What changed - **`jwt-wrapper.service.ts`** — `extractJwtFromRequest()` is now header-only (`ExtractJwt.fromAuthHeaderAsBearerToken()`). No URL fallback anywhere in the system. - **`open-api.service.ts` / `base-schema.utils.ts`** — Dropped the `token?: string` plumbing that propagated the URL token into the schema description. The "Authentication" section gains a "Never put your token in a URL" warning. The "Usage with LLMs" section is rewritten to point at the **Twenty MCP server** (header-authenticated, exposes typed tools — the right tool for AI agents) instead of telling users to paste tokenized OpenAPI URLs into Cursor/ChatGPT. - **`RestPlayground.tsx`** — Now fetches the OpenAPI schema with `Authorization: Bearer ${playgroundApiKey}` and passes the JSON document to Scalar via `spec.content` instead of constructing a URL with `?token=`. Aborts in-flight fetches on unmount/key change. - **New integration test** — Asserts `?token=` is rejected on `/rest/*`, `/graphql`, `/metadata`, and that `/rest/open-api/core?token=` returns the unauthenticated base schema (no workspace object paths). ## Why not keep `?token=` scoped to the OpenAPI endpoint only The first instinct was to narrow the fallback to just `/rest/open-api/*`, since that endpoint is what the Scalar playground component fetches. But the same log-leakage attack still applies to that endpoint — the workspace JWT would still sit in access logs, just from one URL pattern instead of all of them. The cleaner long-term fix is to remove the URL pattern entirely and let the playground fetch with a header (Scalar supports `spec.content` natively). For LLM agent use, the MCP server is a strictly better path — typed tools, OAuth or header-based API key auth, no tokens in URLs anywhere. ## Not affected File downloads at `file-url.service.ts` also use `?token=` URLs but with separate, short-lived `FILE`-typed tokens validated by `file-by-id.guard.ts` directly (not via `extractJwtFromRequest`). That mechanism is scoped per-file with limited TTL and is acceptable. ## Action required for users Anyone who previously pasted `?token=` URLs into LLM tools, scripts, bookmarks, or shared configs should rotate their workspace API keys. Those tokens are likely captured in server logs / chat histories somewhere. ## Test plan - [x] `npx nx typecheck twenty-server` — clean - [x] `npx nx typecheck twenty-front` — clean - [x] `npx nx lint:diff-with-main twenty-server` — clean - [x] `npx nx lint:diff-with-main twenty-front` — clean - [x] OpenAPI utils unit tests + snapshots — 11/11 pass - [ ] Run the new integration test against a live server: `nx run twenty-server:test:integration:with-db-reset` and verify `url-token-auth-rejection.integration-spec.ts` passes - [ ] Manually open Settings → Playground → REST, confirm the schema loads (now via Bearer header instead of `?token=` URL) - [ ] Manually verify `POST /metadata?token=` (no Authorization header) returns Forbidden, and the same request with the token in the header returns the user 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.6 --- .../src/hooks/useNavigateSettings.ts | 32 ++++---- .../navigation/hooks/useOpenSettings.ts | 14 +++- .../playground/components/RestPlayground.tsx | 82 +++++++++++-------- .../RestPlaygroundSchemaFetchEffect.tsx | 40 +++++++++ .../playground/SettingsRestPlayground.tsx | 10 ++- .../jwt/services/jwt-wrapper.service.ts | 15 +--- .../core-modules/open-api/open-api.service.ts | 14 +--- .../open-api/utils/base-schema.utils.ts | 30 ++++--- 8 files changed, 142 insertions(+), 95 deletions(-) create mode 100644 packages/twenty-front/src/modules/settings/playground/components/RestPlaygroundSchemaFetchEffect.tsx diff --git a/packages/twenty-front/src/hooks/useNavigateSettings.ts b/packages/twenty-front/src/hooks/useNavigateSettings.ts index 7889399da4..e1fb794c55 100644 --- a/packages/twenty-front/src/hooks/useNavigateSettings.ts +++ b/packages/twenty-front/src/hooks/useNavigateSettings.ts @@ -1,4 +1,5 @@ import { useOpenSettingsMenu } from '@/navigation/hooks/useOpenSettings';
