Detailsinfo

A vulnerability, which was classified as critical, was found in gitpython-developers GitPython up to 3.1.50. Affected is the function Repo.clone_from of the component Unsafe Option Gate. The manipulation of the argument multi_options with an unknown input leads to a unrestricted upload vulnerability. CWE is classifying the issue as CWE-434. The product allows the attacker to upload or transfer files of dangerous types that can be automatically processed within the product's environment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-67324 since 07/29/2026. The exploitability is told to be easy.
