AI-suggested
A patch is available in GitPython version 2.16.0_8 that fixes this command injection vulnerability by properly validating underscore-form keyword arguments. Users should upgrade to version 2.16.0_8 or later to remediate this issue. Until then, avoid passing untrusted input to the affected API methods or explicitly set 'allow_unsafe_options' to True only if safe. No other mitigations are indicated by the vendor advisory.
Description
GitPython versions from 2.12.0 up to but not including 2.16.0_8 contain a command injection vulnerability due to improper validation of Python keyword arguments that map to unsafe Git command options. Specifically, the use of underscore-form kwargs like 'upload_pack' and 'receive_pack' bypasses the safety checks that block dangerous Git options, allowing arbitrary command execution when attacker-controlled input is passed to certain GitPython API methods.
