{"id":"CVE-2026-45725","aliases":["GHSA-g3vg-vx23-3858","PYSEC-2026-2424"],"url":"https://o3.security/vulnerability/CVE-2026-45725","summary":"compliance-trestle Remote Fetching Mechanism has an Arbitrary File Write via Cache Path Traversal","details":"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.","published":"2026-08-13T19:22:59.118Z","modified":"2026-08-19T03:31:25.918285053Z","cvss":null,"epss":{"score":0.00268,"percentile":0.19069,"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/89f4e53d159e8ff901da4d7c3b51c9556bd32ec0","label":"oscal-compass/compliance-trestle@89f4e53"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45725.json"},{"type":"ADVISORY","url":"https://github.com/oscal-compass/compliance-trestle/security/advisories/GHSA-g3vg-vx23-3858"},{"type":"ADVISORY","url":"https://github.com/pypa/advisory-database/tree/main/vulns/compliance-trestle/PYSEC-2026-2424.yaml"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45725"},{"type":"FIX","url":"https://github.com/oscal-compass/compliance-trestle/commit/89f4e53d159e8ff901da4d7c3b51c9556bd32ec0"},{"type":"FIX","url":"https://github.com/oscal-compass/compliance-trestle/commit/9abc492329fcc8d0557182317de9bde854385da3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T03:31:25.918285053Z"}}
