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.","epss":{"date":"2026-11-03","percentile":0.18967,"score":0.00268},"exploits":[],"kev":null,"metrics":[{"score":7.8,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793717633732,"publishedAt":1784654774394,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:63385"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:63386"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:63387"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-16493"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2503724"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"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 '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."}],"revision":"50046e76355a6fd257beaedc911c2825cd485c230a4161aa75096ef67f5e0cc0","sources":[{"modifiedAt":1793717633732,"name":"CNA: redhat","retrievedAt":1793718614162,"url":"https://www.cve.org/CVERecord?id=CVE-2026-16493"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793718620737,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-16493"}],"ssvc":{"assessedAt":1784730053644,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for cve-2026-11332)","updatedAt":1793718620737}
