This needs to be stated very clearly in the 'rules' for the feature. The
environment should be kept minimal and rescue-focused, to reduce the risk of
security vulnerabilities in the rescue tools. (What if there's an exploit in
wget or curl that can be used to execute arbitrary code when you think
you're just downloading an RPM to fix an issue?)
