CVE-2026-46345: Oscal-Compass Compliance-Trestle

High severity, CVSS 8.4. EPSS: 0.2% chance of exploitation in the next 30 days.

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, before 4.0.3 (fixed in 4.0.3); before 3.12.2 (fixed in 3.12.2)
