Description

Trigger.dev versions prior to 4.5.6 contain a prototype pollution vulnerability in the PUT /api/v1/runs/:runId/metadata endpoint. This flaw allows an attacker with a normal environment API key to modify Object.prototype in the shared webapp process, leading to corruption of Prisma queries and Prometheus labels, breaking authentication for other tenants, and causing a process-wide denial of service. The vulnerability is fixed in version 4.5.6.
