HIGH 7.5UPGRADE
CVE-2026-73623 is a high-severity flaw (CVSS 7.5) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
GitPython before 3.1.54 contains an incomplete denylist in unsafe_git_clone_options that omits --template, allowing attackers to achieve arbitrary command execution during clone operations. Attackers can supply --template pointing to a directory containing malicious post-checkout hooks that execute when git clones the repository.
Why this priority
- High severity
- Public exploit reference
A fixed release or distro patch exists.
