What an attacker can do

Attackers can pass a separate_git_dir parameter to Repo.clone_from() or Repo.clone() to redirect repository metadata to an attacker-controlled filesystem path, enabling arbitrary directory creation and potential hook execution. Vendor/CNA’s CVSS 4.0 assessment (base score 8.7/10) rates confidentiality impact as high; integrity and availability impact as none.
