What is CVE-2026-67323?
CVE-2026-67323 is a high-severity command injection vulnerability in gitpython-developers GitPython, published on 1 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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. Exploitation requires an application that passes attacker-controlled arguments to these methods.
Weakness: CWE-77
