CVE-2026-67326
HIGHGitPython before 3.1.50 Newline Injection via config_writer section
Title source: cnaDescription
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.
