Quick assessment

Affected
triggerdotdev trigger.dev
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Trigger.dev是Trigger.dev组织的一个工作流自动化开发框架。 Trigger.dev 3.3.8版本至4.5.6之前版本存在输入验证错误漏洞，该漏洞源于PUT /api/v1/runs/:runId/metadata端点将攻击者控制的operation.key值传递给JSONHeroPath操作，而未拒绝危险的构造函数和原型路径段，可能导致攻击者污染Object.prototype，破坏Prisma查询和Prometheus标签，破坏其他租户的worker身份验证，并导致进程范围的拒绝服

Vulnerability Title
Trigger.dev: Prototype pollution via run metadata operations → process-wide cross-tenant DoS
Source: CVE Program / CVE List V5
Vulnerability Description
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.
