Vulnerability details
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to improper neutralization of special elements in output used by a downstream component in the GitPython config writer when writing attacker-controlled option names into git configuration files. A remote user can supply a crafted option name to forge git configuration directives and execute arbitrary code.
Exploitation requires an embedding application to pass a caller-influenced option name to the configuration writer, and code execution occurs on a subsequent git operation such as an ssh git action or hook execution.
