What happened?

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
