# Ansible git module lets a dash-prefixed repository URL run commands

Link for people: https://infrastack.ai/live/CVE-2026-84503 (this .md is for agents)

The ansible.builtin.git module passes the repository URL to git without a "--" separator, so a URL starting with a dash is read as a git option. An attacker who controls the URL can use options such as --upload-pack to run arbitrary commands on the host running the module.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed ansible-core version with `ansible --version`.
- Search playbooks and roles for `ansible.builtin.git` or `git:` tasks whose repo value comes from user input, variables, or external data.

## From the sources

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.
