CVE-2026-76221: Gitpython Project Gitpython

High severity, CVSS 8.8. EPSS: 0.8% chance of exploitation in the next 30 days.

GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names. Attackers can inject malicious option names like 'sshCommand = touch /tmp/RCE #' to execute arbitrary commands via core.sshCommand or core.hooksPath on the next git operation.
