CVE-2026-73622
HighCVSS 7.5Summary
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.
Risk Assessment
An attacker could steal sensitive data such as passwords or tokens, potentially leading to security breaches of systems and data.
Recommendation
Upgrade GitPython to version 3.1.55 or later.
