CVE-2026-114086 Details
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.
A missing authentication vulnerability has been identified in Trigger.dev versions prior to 4.5.5. This vulnerability exists in the realtime streams POST handler, where unauthenticated attackers can inject data into run streams. By sending POST requests to the /realtime/v1/streams/:runId/:streamId endpoint with a predictable run friendlyId, attackers can inject arbitrary data into any environment's realtime stream, including production. The vulnerability arises because the POST handler lacks authentication, allowing any entity that knows or guesses a run friendlyId to access and modify the stream data.
Users are advised to update to Trigger.dev version 4.5.5 or later, where this vulnerability has been patched.
