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.

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 'ansible-galaxy collection install -r requirements.yml'. Verify that all collection sources use legitimate HTTPS URLs and do not contain git+ prefixed URIs with suspicious characters (especially values starting with '-').\n\n3. Ensure your system's 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 'ext' unless absolutely required."}], "timeline": [{"lang": "en", "time": "2026-07-21T11:19:29.854Z", "value": "Reported to Red Hat."}, {"lang": "en", "time": "2026-07-21T16:32:48.105Z", "value": "Made public."}], "credits": [{"lang": "en", "value": "Red Hat would like to thank Ta Duc Thien (NTCS) for reporting this issue."}], "providerMetadata": {"orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-07-21T17:26:14.394Z"}, "x_generator": {"engine": "cvelib 1.8.0"}}}}
