High (8.7) in gitpython project gitpython. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in gitpython 3.1.60.
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.
