CVE-2023-40267: OS Command Injection

First published: Fri Aug 11 2023(Updated: )

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.
