HIGH 7.0UPGRADE
CVE-2026-67326 is a high-severity flaw (CVSS 7.0) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
A fixed release or distro patch exists.
