EPSS · scored 2026-10-27

Trigger.dev before 4.5.5 contains a missing authentication vulnerability in the realtime streams POST handler that allows unauthenticated attackers to inject data into run streams. Attackers can send POST requests to /realtime/v1/streams/:runId/:streamId with a predictable run friendlyId to inject arbitrary data into any environment's realtime stream, including production.

  • GHSA-59h8-w5q6-mfmpTrigger.dev: Unauthenticated Realtime Stream Data Injection via Run FriendlyId2026-10-02ghsa · osvUS

    ## Summary The POST handler for `/realtime/v1/streams/:runId/:streamId` has no authentication. Any entity that knows or guesses a run friendlyId can inject arbitrary data into its realtime stream. ## Vulnerability Details **File:** `apps/webapp/app/routes/realtime.v1.streams.$runId.$streamId.ts` The `action` handler (line 17) has no auth wrapper. The code comment says: "Plain action for backwards compatibility with older clients that don't send auth headers." The run lookup at line 29 uses `where: { friendlyId: runId }` with NO environment scoping (`runtimeEnvironmentId` is not checked), so production runs are accessible. Run friendlyIds follow predictable patterns (e.g., `run_1234abcd`). ## Steps to Reproduce ```bash # No authentication required curl -X POST "http://localhost:8030/realtime/v1/streams/run_KNOWN_ID/stream_1" -H "Content-Type: application/json" -d '{"injected": "data"}' ``` ## Impact Unauthenticated data injection into any run realtime stream. Cross-environment access (no scoping).
