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.

          "value": "The following practices would help for avoiding exposure and mitigate this flaw:\n\n1. Do not install Ansible collections from untrusted or unverified git sources. Only install collections from trusted sources such as Ansible Galaxy (https://galaxy.ansible.com), Red Hat Automation Hub (https://console.redhat.com/ansible/automation-hub), or verified internal repositories using HTTPS URLs.\n\n2. Carefully inspect any requirements.yml files before running \u0027ansible-galaxy collection install -r requirements.yml\u0027. Verify that all collection sources use legitimate HTTPS URLs and do not contain git+ prefixed URIs with suspicious characters (especially values starting with \u0027-\u0027).\n\n3. Ensure your system\u0027s git version is 2.12 or later, which disables the ext:: transport by default. While this does not fully prevent exploitation (the -ccore.sshCommand technique bypasses transport restrictions), it eliminates one of the exploitation vectors.\n\n4. Restrict the GIT_ALLOW_PROTOCOL environment variable to only necessary protocols (e.g. https, ssh) and never include \u0027ext\u0027 unless absolutely required."

Only install collections from trusted sources such as Ansible Galaxy (https://galaxy.ansible.com), Red Hat Automation Hub (https://console.redhat.com/ansible/automation-hub), or verified internal repositories using HTTPS URLs.\n\n2. Carefully inspect any requirements.yml files before running \u0027ansible-galaxy collection install -r requirements.yml\u0027. Verify that all collection sources use legitimate HTTPS URLs and do not contain git+ prefixed URIs with suspicious characters (especially values starting with \u0027-\u0027).\n\n3. Ensure your system\u0027s git version is 2.12 or later, which disables the ext:: transport by default. While this does not fully prevent exploitation (the -ccore.sshCommand technique bypasses transport restrictions), it eliminates one of the exploitation vectors.\n\n4. Restrict the GIT_ALLOW_PROTOCOL environment variable to only necessary protocols (e.g. https, ssh) and never include \u0027ext\u0027 unless absolutely required."
