{"id":"CVE-2026-57171","summary":"Trestle is vulnerable to arbitrary file write via path traversal in author generate commands (Incomplete fix of CVE-2026-46345)","details":"Compliance-trestle (Trestle) is a Python SDK and command-line tool for managing OSCAL compliance documents. In versions before 3.12.4 and versions 4.0.0 through 4.0.3, the catalog-generate, profile-generate, and ssp-generate author commands write generated Markdown to an attacker-influenced output path without path-traversal validation, allowing arbitrary file write outside the Trestle workspace. These commands join the user-supplied output argument onto the Trestle root and write to the result, but guard it only with an is_directory_name_allowed() task-name-collision check rather than the PathSecurityValidator.validate_local_path() guard used by the jinja command, so an absolute path or one containing traversal sequences escapes the workspace and writes files under an attacker-chosen location as the invoking process owner. The security boundary is crossed when a trusted CI job, shared service, or wrapper derives the output argument from repository-controlled, tenant-controlled, or otherwise untrusted data while expecting output to stay inside the workspace. When --force-overwrite is used, the selected output directory is first recursively deleted, extending the primitive to destruction of an attacker-chosen directory tree and enabling indirect code execution by overwriting files a pipeline later runs. This issue is fixed in versions 3.12.4 and 4.1.0.","modified":"2026-08-28T03:30:54.784217104Z","published":"2026-08-25T23:39:16.186Z","related":["GHSA-4q5v-7g7x-j79w","GHSA-r4vp-3vw6-r2x5"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57171.json"},"references":[{"type":"WEB","url":"https://github.com/oscal-compass/compliance-trestle/releases/tag/v4.1.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57171.json"},{"type":"ADVISORY","url":"https://github.com/oscal-compass/compliance-trestle/security/advisories/GHSA-4q5v-7g7x-j79w"},{"type":"ADVISORY","url":"https://github.com/oscal-compass/compliance-trestle/security/advisories/GHSA-r4vp-3vw6-r2x5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57171"},{"type":"FIX","url":"https://github.com/oscal-compass/compliance-trestle/commit/37ed44f5f2e074202c8eb7c2f203c05d19461cdc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/oscal-compass/compliance-trestle","events":[{"introduced":"0"},{"fixed":"5855179606e0d0f7656f7455b930ef12d32071e6"},{"introduced":"d965ee5a9a1c2680c80bfa3e63cd75f4fc488881"},{"fixed":"654bfaa0768aa6e4d495911e713c5f4e061e187e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.12.4"},{"introduced":"4.0.0"},{"fixed":"4.1.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.12.3","v4.0.3","v3.12.2","v3.12.1","v4.0.2","v3.12.0","v4.0.1","v4.0.0","v3.11.0","v3.10.4","v3.10.3","v3.10.2","v3.10.1","v3.10.0","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.1","v3.8.0","v3.7.0","v3.6.0","v3.5.0","v3.4.0","v3.3.0","v3.2.0","v3.1.0","v3.0.1","v2.6.1","v2.6.0","v2.5.1","v2.5.0","v2.4.0","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.1","v2.1.0","v2.0.0","v1.2.0","v1.1.0","v1.0.2","v1.0.1","v1.0.0","v0.37.0","v0.36.0","v0.35.0","v0.34.0","v0.33.0","v0.32.1","v0.32.0","v0.31.0","v0.30.0","v0.29.0","v0.28.1","v0.28.0","v0.27.2","v0.27.1","v0.27.0","v0.26.0","v0.25.1","v0.25.0","v0.24.0","v0.23.0","v0.22.1","v0.22.0","v0.21.0","v0.20.0","v0.19.0","v0.18.1","v0.18.0","v0.17.0","v0.16.0","v0.15.1","v0.15.0","v0.14.4","v0.14.3","v0.14.2","v0.14.1","v0.14.0","v0.13.1","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.1","v0.8.0","v0.7.2","v0.7.1","v0.7.0","v0.6.2","v0.6.1","v0.6.0","v0.4.0","v0.3.0","v0.2.2","v0.2.1","v0.2.0","v0.1.1","v0.1.0","v0.0.3","v0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57171.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"}]}
