GHSA-W76H-Q7C6-JPJP
Vulnerability from github – Published: 2026-05-28 18:27 – Updated: 2026-05-28 18:27A source code audit led to the discovery of three significant security vulnerabilities in the trestle/core/remote/cache.py module.
Finding 1 (Critical): SSRF (CWE-918) The 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).
Per rule 4.2.11 of the CVE CNA rules Finding 1 will be addressed in this advisory, while findings 2 & 3 will be addressed in separate advisories:
Multiple Path Traversal Vulnerabilities in Remote Fetching Subsystem
Finding 2 & 3 (High/Medium): Path Traversal (CWE-22) The 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.
Impact: > These vulnerabilities can be chained to exfiltrate sensitive cloud credentials or compromise CI/CD environments.
Reproduction: > Please see the attached poc_ssrf_and_path_traversal.py and terminal_output.txt. 13 exploit vectors have been verified locally.
