CVE-2026-16493 (GCVE-0-2026-16493)

Vulnerability from cvelistv5 – Published: 2026-07-21 17:26 – Updated: 2026-07-22 14:21

Title

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

Summary

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)
