Detailsinfo

A vulnerability was found in gitpython-developers GitPython up to 3.1.54. It has been rated as problematic. This issue affects the function Remote.create/Submodule.add of the component URL Handler. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78.

Impacted is confidentiality. The summary by CVE is:

GitPython before 3.1.55 fails to disable environment variable expansion in Remote.create() and Submodule.add() URL handling, allowing attackers to exfiltrate secrets by supplying URLs containing variable references. Attackers can craft URLs with environment variable tokens that are expanded into .git/config and .gitmodules, then transmitted to attacker-controlled hosts during fetch or pull operations.
