CVE-2026-16493 – Ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for cve-2026-11332)

CVE ID :CVE-2026-16493

Published : July 21, 2026, 5:26 p.m. | 18 minutes ago

Description :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.

Severity: 7.8 | HIGH
