{"id":"CVE-2026-45774","state":"PUBLISHED","title":"compliance-trestle Profile Import has an Arbitrary File Read via trestle:// URI and Relative Path Traversal","description":"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.","publishedAt":"2026-08-13T19:26:44.243Z","updatedAt":"2026-08-14T17:04:38.615Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["oscal-compass compliance-trestle"],"affected":[{"vendor":"oscal-compass","product":"compliance-trestle","versions":[{"version":"< 3.12.2","status":"affected"},{"version":">= 4.0.0, < 4.0.3","status":"affected"}]}],"references":["https://github.com/oscal-compass/compliance-trestle/security/advisories/GHSA-mj4x-vf5c-5xg8","https://github.com/oscal-compass/compliance-trestle/commit/5c65c5926fe7ca908b9c1d281f904e7d97ba8310","https://github.com/oscal-compass/compliance-trestle/commit/d00a0c2f702c24f7016009fbd626036f5c46f47b","https://github.com/pypa/advisory-database/tree/main/vulns/compliance-trestle/PYSEC-2026-2426.yaml"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/45xxx/CVE-2026-45774.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-45774","state":"PUBLISHED","datePublished":"2026-08-13T19:26:44.243Z","dateUpdated":"2026-08-14T17:04:38.615Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-13T07:45:21.251Z"},"containers":{"cna":{"title":"compliance-trestle Profile Import has an Arbitrary File Read via trestle:// URI and Relative Path Traversal","descriptions":[{"lang":"en","value":"compliance-trestle is a tooling platform for managing compliance as code.
