CVE-2026-73623 PUBLISHED

GitPython before 3.1.54 Remote Code Execution via --template

Assigner: VulnCheck
Reserved: 13.08.2026 Published: 13.08.2026 Updated: 13.08.2026

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.
