CVE-2026-67326: Gitpython Project Gitpython

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

GitPython before 3.1.50 fails to validate newline characters in the section parameter of config_writer(), allowing attackers to inject arbitrary section headers into .git/config. Attackers can inject newlines to create a forged [core] section with hooksPath pointing to attacker-controlled directories, achieving remote code execution when git hooks are triggered.

Affected products

• Gitpython Project Gitpython: before 3.1.50 (fixed in 3.1.50)
