Doc Text:	A flaw was found in compliance-trestle. The library's profile import mechanism, which handles `trestle://` URIs and relative file paths, does not properly validate paths. This allows a remote attacker to craft a malicious OSCAL (Open Security Controls Assessment Language) profile YAML file containing path traversal sequences. Successful exploitation could enable the attacker to read arbitrary files from the server's filesystem, potentially leading to sensitive information disclosure.	Story Points:	---

Description OSIDB Bzimport 2026-08-13 19:59:36 UTC

compliance-trestle is a tooling platform for managing compliance as code. Prior to versiions 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.
