Overview

CVE-2026-84502 is a critical-severity vulnerability. It was published on September 23, 2026 and has a CVSS 3.1 base score of 9.9 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.9, rated CRITICAL. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

A flaw was found in Red Hat Ansible Automation Platform's automation-

controller. The Project scm_url field is not validated against values that

begin with a dash and is stored and passed verbatim to the git SCM module.

Because the module runs git ls-remote with the URL as a positional argument and

without a "--" separator, a git project URL such as "--upload-pack=<command>:x"

is interpreted by git as the --upload-pack option and executed via a shell. A

user with permission to create or modify a project in a single organization can

thereby execute arbitrary commands on the control-plane task pod, with output

reflected through the project update stdout endpoint, leading to cross-tenant

compromise and in-cluster lateral movement

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
