CVE-2026-67324
CriticalCVSS 9.8Summary
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.
Risk Assessment
The risk is that an attacker can execute arbitrary commands during repository cloning, potentially compromising system security.
Recommendation
Upgrade GitPython to version 3.1.51 or later.
