What is CVE-2026-16493?

A vulnerability exists in Ansible Core where the _extract_collection_from_git() function constructs git clone commands without a proper separator before user-supplied URLs. This oversight permits an attacker to provide a malicious collection source URI with crafted payloads, leading to arbitrary command execution upon executing 'ansible-galaxy collection install'. The flaw is a continuation of issues addressed in a prior fix, which targeted the role install path but overlooked the similar collection install procedures.
