Medium (6.7). EPSS 0.2% estimated probability of exploitation activity in the next 30 days.

A flaw was found in ansible-core's ansible.builtin.git module. The module
invokes git (ls-remote, clone, fetch) with the repository URL as a positional
argument and without a "--" separator, so a repository URL that begins with a
dash is interpreted by git as a command-line option. A caller that passes an
attacker-controlled repository URL to the module can trigger argument
injection (for example --upload-pack/--exec), resulting in arbitrary command
execution on the host running the module.

Red Hat
Red Hat rates this Moderate.
This flaw affects automation-controller as shipped in Red Hat Ansible
Automation Platform, and the underlying argument-injection behavior in the
ansible-core git module. The controller does not reject project SCM URLs that
begin with a dash and the git module does not separate options from the
repository argument, allowing command execution on the control-plane task pod.
