Summary

Duplicate Advisory: GitPython unsafe clone option gate bypass through joined short options

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-v396-v7q4-x2qj. This link is maintained to preserve external references.

Original Description

GitPython 3.1.50 fails to recognize joined short-option forms such as -u (the short form of --upload-pack=) when enforcing its default unsafe-option gate. When an application passes attacker-influenced clone options into Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), an attacker can supply -u to bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper command during clone. Fixed in 3.1.51.

Vulnerability from cvelistv5 – Published: 2026-08-01 12:22 – Updated: 2026-08-14 16:50

Title

GitPython 3.1.50 Authentication Bypass via Joined Short Options

Summary

GitPython 3.1.50 fails to recognize joined short-option forms such as -u<value> (the short form of --upload-pack=<value>) when enforcing its default unsafe-option gate. When an application passes attacker-influenced clone options into Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), an attacker can supply -u<helper> to bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper command during clone. Fixed in 3.1.51.
