Input validation error in GitPython - CVE-2026-67326

Vulnerability identifier: #VU131003

CSH Severity: Medium

CVSS v4: 7.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-67326

CWE-ID: CWE-20

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper input validation in config_writer() and set_value() in git/config.py when processing a crafted section parameter containing newline characters. A remote attacker can supply a crafted section name to inject arbitrary section headers into .git/config and execute arbitrary code.

User interaction is required to trigger a git hook after the malicious configuration is written.
