When installing a collection with\n`ansible-galaxy collection install`, the archive extractor validates member\npaths using lexical path normalisation (os.path.abspath) instead of resolving\nsymbolic links (os.path.realpath), and it performs no containment check on\nsymlink-typed directory members before creating them. A crafted collection\ntarball can chain symlink directory entries so that a subsequent file member is\nwritten outside the intended destination directory. This allows an attacker who\ncan get a victim to install a malicious collection to overwrite arbitrary files\nwith the privileges of the user running ansible-galaxy, leading to code\nexecution on the control node. This is a bypass of the fix for CVE-2020-10691.","state":"PUBLISHED","assigner":"redhat","published_at":"2026-10-08 22:17:35","updated_at":"2026-10-09 16:37:45"},"problem_types":["CWE-59","CWE-59
