HIGH 8.8UPGRADE
CVE-2026-76221 is a high-severity flaw (CVSS 8.8) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
A fixed release or distro patch exists.
