Description

compliance-trestle is a tooling platform for managing compliance as code. Prior to versions 3.12.2 and 4.0.3, the `-o/--output` argument in `trestle author jinja` allows writing files outside the intended workspace. The application does not properly validate, `../`, `..\`, or absolute paths. This allows arbitrary file write to attacker-controlled locations. Versions 3.12.3 and 4.0.3 patch the issue.

Affected products

• oscal-compass compliance-trestle: from 4.0.0, < 4.0.3; before 3.12.2
