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