Vulnerability Title
GitPython before 3.1.55 Environment Variable Exfiltration via Remote.add()
Source: CVE Program / CVE List V5
Vulnerability Description
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.
