Description

GitPython before 3.1.60 contains a regular expression denial of service vulnerability in Actor.name_email_regex that processes commit author and committer fields. Attackers can craft a commit object with a malformed author field containing an unterminated angle bracket to cause quadratic backtracking, exhausting CPU resources for over two minutes per commit access.

Detection & mitigation playbook

Vulnerability
  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Fix

    Upgrade the affected component to the fixed release for GHSA-g5vv-9gxw-82hx, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

A regular expression denial of service vulnerability was found in GitPython when processing commit author and committer fields. The Actor.name_email_regex pattern exhibits quadratic backtracking when encountering malformed author fields containing unterminated angle brackets. An attacker who can introduce a crafted…

Workaround published by Red Hat
Update GitPython to version 3.1.60 or later. Validate and sanitize git repository sources before processing. Enable git fsck validation (receive.fsckObjects) on git servers to reject malformed commit objects. Implement length limits on commit metadata fields before processing.
