CVE-2026-73654 is a prototype-pollution vulnerability in Trigger.dev versions 3.3.8 through versions before 4.5.6. The run-metadata update functionality passes an attacker-controlled metadata operation key to JSONHeroPath.set() without rejecting dangerous prototype-related path segments. This permits modification of Object.prototype within the shared web application process.

A high-severity prototype-pollution vulnerability in @trigger.dev/core (Trigger.dev), affecting versions 3.3.8 through before 4.5.6. An authenticated caller with a normal environment API key can supply crafted metadata operation keys to pollute Object.prototype in the shared web application process, potentially causing cross-tenant worker-authentication disruption, corruption of Prisma queries and Prometheus labels, and process-wide denial of service.
A prototype pollution vulnerability in Trigger.dev metadata handling that allows unsafe JSON path input to reach the path resolver and modify Object.prototype, leading to integrity impact and denial of service in affected self-hosted instances.
A prototype pollution vulnerability in Trigger.dev's PUT /api/v1/runs/:runId/metadata endpoint that allows an authenticated caller with a normal environment API key to pollute Object.prototype in the shared webapp process, leading to integrity impact across tenants and process-wide denial of service.
