Path traversal in GitPython - CVE-2026-76222

Vulnerability identifier: #VU140975

CSH Severity: High

CVSS v4: 7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-76222

CWE-ID: CWE-22

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to create arbitrary Git repositories outside the working tree.

The vulnerability exists due to path traversal in submodule initialization logic when processing a cloned repository's .gitmodules submodule name during submodule initialization. A remote attacker can supply a specially crafted repository with a traversal string in the submodule name to create arbitrary Git repositories outside the working tree.

User interaction is required to clone the malicious repository and run submodule initialization.
