CVE-2026-16493

A flaw was found in ansible-core. The _extract_collection_from_git() function in ansible-core's concrete_artifact_manager.py constructs git clone commands without a '--' (end-of-options) separator before user-supplied URLs when installing collections from git sources. An attacker who provides a crafted collection source URI containing git argument injection payloads can achieve arbitrary command execution when a user runs 'ansible-galaxy collection install' with the malicious source. This is an incomplete fix for CVE-2026-11332, which hardened the role install path but missed the equivalent collection install code path.
