AI-suggested

A fix is available in GitPython version 1.2.0.post0_12 that disables environment variable expansion in these URL handling functions. Users should upgrade to this version or later to remediate the vulnerability.

Description

GitPython versions prior to 1.2.0.post0_12 contain a vulnerability where environment variables in URLs passed to Repo.create_remote() or Remote.add() are expanded and embedded into the repository configuration. This can lead to sensitive environment variables being written into .git/config and transmitted to attacker-controlled hosts during fetch or pull operations.
