Description

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.
