What an attacker can do

Attackers can craft a repository where a worktree symlink points to .git/hooks/post-checkout, so restoring the file from a tag writes a malicious hook for code execution. Vendor/CNA’s CVSS 4.0 assessment (base score 7.3/10) rates confidentiality, integrity and availability impact as high.
