GitPython Remote.pull() refspec bypasses the --upload-pack unsafe-option guard, enabling arbitrary command execution

Remote.pull() in GitPython forwards its positional refspec argument directly to the git pull child process while its unsafe-option guard inspects only keyword arguments. An application that passes attacker-influenced data as the refspec (for example a user-supplied branch or refspec parameter in a web or CI service) can supply an option-shaped value such as --upload-pack= .
