Detailsinfo

A vulnerability classified as critical was found in Red Hat Ansible Automation Platform Ansible Core (version unknown). This vulnerability affects an unknown function of the component ansible.builtin.git. The manipulation of the argument repository URL with an unknown input leads to a command injection vulnerability. The CWE definition for the vulnerability is CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at access.redhat.com. This vulnerability was named CVE-2026-84503 since 09/01/2026. The exploitation appears to be easy. The attack can be initiated remotely. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 11/09/2026). The MITRE ATT&CK project declares the attack technique as T1202.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
