CVE-2026-114086: Trigger.dev missing authentication in realtime streams POST handler

CVE-2026-114086 · Severity: medium · CVSS 5.3 · Published 2026-10-21

Trigger.dev is a platform for orchestrating background jobs and automating workflows. An unauthenticated attacker can inject malicious data into real-time job streams by guessing predictable job identifiers, potentially corrupting job output and affecting production environments. This allows arbitrary data injection without requiring any credentials or authentication.

Technologies: Trigger.dev. Vendors: Trigger.dev.

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.
