AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Attacker needs no privileges (PR:N) but the victim must locally run the install command (AV:L/UI:R); injected command runs as that user with full C/I/A impact and no scope change.

Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Arbitrary command execution in ansible-core allows an attacker who controls a collection source URI to run commands on a victim's machine when that victim executes 'ansible-galaxy collection install' against the malicious git source. The flaw lives in _extract_collection_from_git() in concrete_artifact_manager.py, which builds git clone commands without a '--' end-of-options separator, letting crafted URIs be parsed as git arguments. It is an incomplete fix for CVE-2026-11332, which patched the analogous role-install path but left the collection-install path exposed; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Technical ContextAI
ansible-core is the execution engine underneath Ansible and Red Hat Ansible Automation Platform, and ansible-galaxy is its bundled content-management CLI used to fetch roles and collections, including directly from git repositories. When resolving a git-sourced collection, _extract_collection_from_git() assembles a 'git clone' invocation and interpolates the user-supplied source URI into the argument list. Because no '--' separator precedes the URI, a value beginning with '-' (for example an --upload-pack or --config style option, or ext:: transport tricks) is interpreted by git as an option rather than a positional URL. This is the CWE-88 (Argument Injection/Improper Neutralization of Argument Delimiters) root-cause class: the trust boundary between data (the repository location) and control (git's own flags) is not enforced, so attacker data is promoted to command options. The CPE set scopes this to Red Hat's packaged ansible-core across Red Hat Ansible Automation Platform 2, RHEL 8/9/10, and Red Hat Satellite 6.
RemediationAI
No vendor-released patch version was identified in the provided data, so the primary action is to monitor and apply the Red Hat erratum referenced at https://access.redhat.com/security/cve/CVE-2026-16493 and track https://bugzilla.redhat.com/show_bug.cgi?id=2503724 for the fixed ansible-core package versions across RHEL 8/9/10, Ansible Automation Platform 2, and Satellite 6, then upgrade to those releases once published. As a compensating control until patched, do not run 'ansible-galaxy collection install' against untrusted or attacker-influenced git source URIs, and pin collection installs to vetted, trusted sources or Automation Hub/private Galaxy mirrors rather than arbitrary git URLs (trade-off: loses the convenience of ad-hoc git installs). Where feasible, review any requirements.yml or automation pipeline that accepts externally supplied collection sources and reject URIs beginning with '-' or using non-standard git transports such as ext::, and run galaxy installs under a low-privilege, sandboxed account to limit the blast radius of any injected command (trade-off: added operational friction in CI/CD).
