GitPython vulnerable to remote code execution due to insufficient sanitization of input arguments

Critical severity GitHub Reviewed Published Aug 11, 2023 to the GitHub Advisory Database • Updated Nov 10, 2023

Package

pip GitPython (pip)

Affected versions

< 3.1.32

Patched versions

3.1.32

Description

GitPython before 3.1.32 does not block insecure non-multi options in clone and clone_from, making it vulnerable to Remote Code Execution (RCE) due to improper user input validation, which makes it possible to inject a maliciously crafted remote URL into the clone command. Exploiting this vulnerability is possible because the library makes external calls to git without sufficient sanitization of input arguments. NOTE: this issue exists because of an incomplete fix for CVE-2022-24439.
