# CVE-2026-84502: Automation-controller: automation-controller-container: automation-controller: project scm_url argument injection into `git ls-remote --upload-pack` yields rce on the controller-task control-plane pod

Status: published. Published: 2026-09-23. Updated: 2026-11-02.

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
