CVE-2026-73654
HighCVSS 8.5Exploitation Probability (EPSS)
Low risk26th percentile - higher than 26% of all known CVEs
Summary
Trigger.dev from version 3.3.8 to 4.5.6 contains a vulnerability in the PUT /api/v1/runs/:runId/metadata endpoint, where operation.key values are passed to new JSONHeroPath(operation.key).set() without rejecting dangerous constructor and prototype path segments. A caller with a normal environment API key can pollute Object.prototype in the shared webapp process, corrupting Prisma queries and Prometheus labels, breaking other tenants' worker authentication, and causing a process-wide denial of service.
Risk Assessment
An attacker could cause denial of service, break tenant isolation, and disrupt the entire platform.
Recommendation
Upgrade Trigger.dev to version 4.5.6 or later, which includes the fix.
Original NVD description (English source)
Trigger.dev is a platform for building and deploying fully managed AI agents and workflows. From 3.3.8 until 4.5.6, the PUT /api/v1/runs/:runId/metadata endpoint passes attacker-controlled operation.key values to new JSONHeroPath(operation.key).set(newMetadata, value) in packages/core/src/v3/runMetadata/operations.ts without rejecting dangerous constructor and prototype path segments. A caller with a normal environment API key can pollute Object.prototype in the shared webapp process, corrupting Prisma queries and Prometheus labels, breaking other tenants' worker authentication, and causing a process-wide denial of service. This issue is fixed in version 4.5.6.
