CVE-2026-73659
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.
