{"id":"CVE-2026-45725","state":"PUBLISHED","title":"compliance-trestle Remote Fetching Mechanism has an Arbitrary File Write via Cache Path Traversal","description":"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 remote fetching cache mechanism (HTTPSFetcher and SFTPFetcher) constructs the local cache file path from the URL path component without sanitizing path traversal sequences (`../`). When a remote OSCAL profile references a URL with traversal in its path, the HTTP response body is written to a location outside the intended cache directory, enabling arbitrary file write with attacker-controlled content to the filesystem. Versions 3.12.3 and 4.0.3 patch the issue.","publishedAt":"2026-08-13T19:22:59.118Z","updatedAt":"2026-08-17T18:18:06.770Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/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-g3vg-vx23-3858","https://github.com/oscal-compass/compliance-trestle/commit/89f4e53d159e8ff901da4d7c3b51c9556bd32ec0","https://github.com/oscal-compass/compliance-trestle/commit/9abc492329fcc8d0557182317de9bde854385da3","https://github.com/pypa/advisory-database/tree/main/vulns/compliance-trestle/PYSEC-2026-2424.yaml"],"weaknesses":["CWE-73"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/45xxx/CVE-2026-45725.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-45725","state":"PUBLISHED","datePublished":"2026-08-13T19:22:59.118Z","dateUpdated":"2026-08-17T18:18:06.770Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-13T05:51:48.666Z"},"containers":{"cna":{"title":"compliance-trestle Remote Fetching Mechanism has an Arbitrary File Write via Cache Path Traversal","descriptions":[{"lang":"en","value":"compliance-trestle is a tooling platform for managing compliance as code.
