The pygmalion and pygmalion-virtualenv themes unsafely handle git prompt information which results in a double evaluation of this information, so a malicious git repository could trigger a command injection if the user cloned and entered the repository. A similar method could be used in the refined theme. All themes have been patched against this vulnerability.
