HIGH 8.4UPGRADE

CVE-2026-67323 is a high-severity flaw (CVSS 8.4) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output=<path> can cause Git to open and truncate an arbitrary file.
