Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to incomplete list of disallowed inputs in the check_unsafe_options option validation in GitPython when processing attacker-controlled keyword argument keys for git clone, fetch, pull, or push operations. A remote user can supply a specially crafted abbreviated long option to execute arbitrary code.
Exploitation requires a host application to pass attacker-controlled keyword argument keys into affected GitPython operations while using the default unsafe-option protection.
