The returned task objects include the task IDs and payloads. The same task IDs can then be used with the capability-style task mutation endpoints (`/tasks/:id/claim`, `/tasks/:id/result`, `/tasks/:id/complete`, `/tasks/:id/fail`) to claim, complete, or fail tasks assigned to a different agent.\n\nBecause ordinary authenticated agents can discover agent names through `GET /api/agenticmail/accounts/directory`, the task ID effectively stops being a secret capability. This turns the intended capability model into a cross-agent authorization bypass.\n\n## Affected component\n\nPackage: `@agenticmail/api`\nObserved version: `0.9.62`\nRepository: `agenticmail/agenticmail`\n\nRelevant code paths:\n\n- `packages/api/src/app.ts`: `createAuthMiddleware(...)` is mounted before `createAccountRoutes(...)` and `createTaskRoutes(...)`, so these routes are reachable by any valid bearer token.\n- `packages/api/src/routes/accounts.ts`: `GET /accounts/directory` is available to any authenticated user and returns ","public_affected_ranges":["< 0.9.64"]}],"null_published_at":"2026-11-04T10:04:27.932Z","source_updated_at":"2026-07-20T22:00:54.000Z","source_disclosed_at":"2026-06-18T17:20:55.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T22:35:18.117Z"}],"next_cursor":null,"snapshot_revision":"42594"}
