CVE-2026-67322 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.

An attacker who controls the clone URL can embed $NAME or ${NAME} tokens that are expanded to the values of the hosting process's environment variables (e.g., AWS_SECRET_ACCESS_KEY or GITHUB_
Why this priority
