{"id":"PYSEC-2026-2427","summary":"compliance-trestle Vulnerable to SSRF in Remote Fetching Subsystem","details":"A source code audit led to the discovery of three significant security vulnerabilities in the trestle/core/remote/cache.py module.\n\n**Finding 1 (Critical): SSRF (CWE-918)**\nThe HTTPSFetcher._do_fetch() method passes a user-supplied URL directly to requests.get() without validation. This allows an attacker to perform Server-Side Request Forgery, targeting internal services or cloud metadata endpoints (e.g., 169.254.169.254).\n\nPer [rule 4.2.11 of the CVE CNA rules](https://www.cve.org/ResourcesSupport/AllResources/CNARules#section_4-2_CVE_ID_Assignment) Finding 1 will be addressed in this advisory, while findings 2 & 3 will be addressed in separate advisories:\n\n---\n\nMultiple Path Traversal Vulnerabilities in Remote Fetching Subsystem\n\n**Finding 2 & 3 (High/Medium): Path Traversal (CWE-22)**\nThe caching logic for HTTPSFetcher and LocalFetcher fails to sanitize URI paths, allowing for arbitrary file reads via file:// or writing cached files outside the intended directory.\n\nImpact: \u003e These vulnerabilities can be chained to exfiltrate sensitive cloud credentials or compromise CI/CD environments.\n\nReproduction: \u003e Please see the attached poc_ssrf_and_path_traversal.py and terminal_output.txt. 13 exploit vectors have been verified locally.\n\n[compliance-trestle_audit_2026-03-30.pdf](https://github.com/user-attachments/files/26348930/compliance-trestle_audit_2026-03-30.pdf)\n[poc_ssrf_and_path_traversal.py](https://github.com/user-attachments/files/26348820/poc_ssrf_and_path_traversal.py)\n[terminal_output.txt](https://github.com/user-attachments/files/26348821/terminal_output.txt)","aliases":["CVE-2026-46380","GHSA-w76h-q7c6-jpjp"],"modified":"2026-07-13T16:32:36.325752689Z","published":"2026-07-13T15:19:13.146792Z","references":[{"type":"WEB","url":"https://github.com/oscal-compass/compliance-trestle/security/advisories/GHSA-w76h-q7c6-jpjp"},{"type":"WEB","url":"https://github.com/oscal-compass/compliance-trestle/commit/53de5e75332888ea54f5da41d4c7859bb1d608e1"},{"type":"WEB","url":"https://github.com/oscal-compass/compliance-trestle/commit/5c65c5926fe7ca908b9c1d281f904e7d97ba8310"},{"type":"PACKAGE","url":"https://github.com/oscal-compass/compliance-trestle"},{"type":"PACKAGE","url":"https://pypi.org/project/compliance-trestle"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-w76h-q7c6-jpjp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46380"}],"affected":[{"package":{"name":"compliance-trestle","ecosystem":"PyPI","purl":"pkg:pypi/compliance-trestle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.12.2"},{"introduced":"4.0.0"},{"fixed":"4.0.3"}]}],"versions":["0.0.2","0.0.3","0.1.0","0.1.1","0.10.0","0.11.0","0.12.0","0.13.0","0.13.1","0.14.0","0.14.1","0.14.2","0.14.3","0.14.4","0.15.0","0.15.1","0.16.0","0.17.0","0.18.0","0.18.1","0.19.0","0.2.0","0.2.1","0.2.2","0.20.0","0.21.0","0.22.0","0.22.1","0.23.0","0.24.0","0.25.0","0.25.1","0.26.0","0.27.0","0.27.1","0.27.2","0.28.0","0.28.1","0.29.0","0.3.0","0.30.0","0.31.0","0.32.0","0.32.1","0.33.0","0.34.0","0.35.0","0.36.0","0.37.0","0.4.0","0.5.0","0.6.0","0.6.1","0.6.2","0.7.0","0.7.1","0.7.2","0.8.0","0.8.1","0.9.0","1.0.0rc0","1.0.1","1.0.2","1.1.0","1.2.0","2.0.0","2.1.0","2.1.1","2.2.0","2.2.1","2.3.0","2.3.1","2.4.0","2.5.0","2.5.1","2.6.0","2.6.1","3.0.1","3.1.0","3.10.2","3.10.3","3.10.4","3.11.0","3.12.0","3.12.1","3.2.0","3.3.0","3.4.0","3.5.0","3.6.0","3.7.0","3.8.0","3.8.1","3.9.0","3.9.1","3.9.2","3.9.3","4.0.0","4.0.1","4.0.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/compliance-trestle/PYSEC-2026-2427.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N"}]}
