Summary
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.
A flaw was found in GitPython. An incomplete denylist in the `unsafe_git_clone_options` function fails to restrict the `--template` option.
This allows a remote attacker to supply a malicious Git template directory, leading to arbitrary command execution during clone operations. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).
Weakness: CWE-78.
