Technical details
The /realtime/v1/streams/:runId/:streamId POST handler lacks authentication despite handling sensitive real-time data injection. The vulnerability exploits predictable run friendlyIds (e.g., run_1234abcd) and the absence of environment scoping in the run lookup, allowing cross-environment access including production. An attacker can send unauthenticated POST requests with arbitrary JSON payloads to inject data into any run's stream.
