    "title": "Trigger.dev: Unauthenticated Realtime Stream Data Injection via Run FriendlyId",
    "summary": "## 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).",
