Doc Text:
A flaw was found in GitPython. This vulnerability allows a remote attacker to exfiltrate sensitive information, such as environment variables, by crafting malicious URLs. When these URLs are processed during Git operations like fetch or pull, the environment variables are expanded and transmitted to attacker-controlled hosts, leading to information disclosure.

Description OSIDB Bzimport 2026-08-13 12:18:33 UTC
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.
