{"id":"CVE-2026-45774","aliases":["GHSA-mj4x-vf5c-5xg8","PYSEC-2026-2426"],"url":"https://o3.security/vulnerability/CVE-2026-45774","summary":"compliance-trestle Profile Import has an Arbitrary File Read via trestle:// URI and Relative Path Traversal","details":"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.","published":"2026-08-13T19:26:44.243Z","modified":"2026-08-16T03:31:12.867420524Z","cvss":null,"epss":{"score":0.00371,"percentile":0.30316,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"compliance-trestle","fixedVersion":"4.0.3"},{"ecosystem":"PyPI","name":"compliance-trestle","fixedVersion":"3.12.2"}],"fix":{"url":"https://github.com/oscal-compass/compliance-trestle/commit/5c65c5926fe7ca908b9c1d281f904e7d97ba8310","label":"oscal-compass/compliance-trestle@5c65c59"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45774.json"},{"type":"ADVISORY","url":"https://github.com/oscal-compass/compliance-trestle/security/advisories/GHSA-mj4x-vf5c-5xg8"},{"type":"ADVISORY","url":"https://github.com/pypa/advisory-database/tree/main/vulns/compliance-trestle/PYSEC-2026-2426.yaml"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45774"},{"type":"FIX","url":"https://github.com/oscal-compass/compliance-trestle/commit/5c65c5926fe7ca908b9c1d281f904e7d97ba8310"},{"type":"FIX","url":"https://github.com/oscal-compass/compliance-trestle/commit/d00a0c2f702c24f7016009fbd626036f5c46f47b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:31:12.867420524Z"}}
