It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-57171 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- compliance-trestle (PyPI): affected all versions; fixed in 3.12.4, 4.1.0\n- compliance-trestle (PyPI): affected all versions; fixed in 3.12.4\n- compliance-trestle (PyPI): affected all versions; fixed in 3.12.4\n- compliance-trestle (PyPI): affected from 4.0.0; fixed in 4.1.0\n- compliance-trestle (PyPI): affected from 4.0.0; fixed in 4.1.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-57171/ (Markdown: https://insights.sbomify.com/CVE-2026-57171/index.md)","id":"CVE-2026-57171","markdown":"https://insights.sbomify.com/CVE-2026-57171/index.md","name":"CVE-2026-57171","record":{"aliases":["GHSA-r4vp-3vw6-r2x5","PYSEC-2026-4030"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OSCAL compliance tool","requires_auth":"none","summary":"Attackers can write arbitrary files or delete directories via path traversal in Trestle generate commands, potentially leading to code execution in CI pipelines.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"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.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Trestle is vulnerable to arbitrary file write via path traversal in author generate commands (Incomplete fix of CVE-2026-46345)","id":"CVE-2026-57171","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":5,"n_references":4,"next":{"headline":"DataEase: Hardcoded JWT Signing Secret in ShareLink","id":"CVE-2026-57172"},"packages":[{"ecosystem":"PyPI","fixed":["3.12.4","4.1.0"],"introduced":["0","4.0.0"],"last_affected":[],"package":"compliance-trestle","purl":"pkg:pypi/compliance-trestle","source":"PYSEC-2026-4030"},{"ecosystem":"PyPI","fixed":["3.12.4"],"introduced":["0"],"last_affected":[],"package":"compliance-trestle","purl":null,"source":"GHSA-r4vp-3vw6-r2x5"},{"ecosystem":"PyPI","fixed":["3.12.4"],"introduced":["0"],"last_affected":[],"package":"compliance-trestle","purl":"pkg:pypi/compliance-trestle","source":"GHSA-r4vp-3vw6-r2x5"},{"ecosystem":"PyPI","fixed":["4.1.0"],"introduced":["4.0.0"],"last_affected":[],"package":"compliance-trestle","purl":null,"source":"GHSA-r4vp-3vw6-r2x5"},{"ecosystem":"PyPI","fixed":["4.1.0"],"introduced":["4.0.0"],"last_affected":[],"package":"compliance-trestle","purl":"pkg:pypi/compliance-trestle","source":"GHSA-r4vp-3vw6-r2x5"}],"prev":{"headline":"Trestle SSTI in Jinja2 include tags allows arbitrary code execution (Incomplete fix of CVE-2026-46439)","id":"CVE-2026-57170"},"products":["compliance-trestle"],"published":"2026-08-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["oscal-compass"]},"summary":"Attackers can write arbitrary files or delete directories via path traversal in Trestle generate commands, potentially leading to code execution in CI pipelines.","url":"https://insights.sbomify.com/CVE-2026-57171/"}
