CVE-2026-45774
compliance-trestle Profile Import has an Arbitrary File Read via trestle:// URI and Relative Path Traversal
Impact
compliance-trestle is a tooling platform for managing compliance as code. Prior to versions 3.12.2 and 4.0.3, the compliance-trestle library's profile import mechanism resolves `trestle://` URIs and relative file paths by joining them with `trestle_root` and calling `.resolve()`, but performs no boundary check to ensure the resolved path stays within the trestle workspace. An attacker can craft a malicious OSCAL profile YAML with `imports[].href` containing path traversal sequences to read arbitrary files from the server filesystem. Versions 3.12.3 and 4.0.3 patch the issue.
