Summary

Trigger.dev before 4.5.0-rc.3 contains a path traversal vulnerability in the api/v1/packets and api/v2/packets endpoints. An authenticated tenant holding one valid API key can supply ../ sequences in an unsanitized filename splat segment to escape its object key prefix. The attacker can then obtain presigned GET or PUT URLs to read or overwrite other tenants' run payloads and outputs.
