Overview
Affected versions of this package are vulnerable to Command Injection via the repo-server process when cloning, testing, or fetching an SSH Git repository configured with a crafted proxy URL. An attacker can execute arbitrary commands on the server by supplying a specially crafted proxy host value, which is embedded in an SSH ProxyCommand and executed through a shell without proper neutralization of shell metacharacters. This allows access to sensitive credentials such as Git, Helm, and OCI credentials by users who can create or update a repository or repository credential template.
