CVE-2026-73659— Trigger.dev: Cross-tenant object read/write via path traversal in packet presign API

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 4.4.2版本至4.5.0之前版本存在路径遍历漏洞，该漏洞源于apps/webapp/app/routes/api.v1.packets.$.ts中的数据包预签名路由将调用者控制的文件名传递给generatePresignedUrl，导致路径遍历，可能允许项目API密钥读取或覆盖其他组织的任务负载和输出。

Vulnerability Title
Trigger.dev: Cross-tenant object read/write via path traversal in packet presign API
Source: CVE Program / CVE List V5
Vulnerability Description
Trigger.dev is the open-source platform for building AI workflows in TypeScript. From 4.4.2 until 4.5.0, the packet presign routes in apps/webapp/app/routes/api.v1.packets.$.ts pass a caller-controlled filename through resolveStoreProtocolForPacketPresign to generatePresignedUrl and generatePresignedRequest in apps/webapp/app/v3/objectStore.server.ts, allowing .. traversal to escape the packets/<projectRef>/<env>/ object-store prefix and enabling a project API key to read or overwrite another organization's offloaded task payloads and outputs on multi-organization self-hosted instances. This issue is fixed in version 4.5.0.
