A flaw was found in extract-zip. This vulnerability allows a remote attacker to perform an arbitrary file write outside the intended destination directory. By crafting a malicious zip archive containing a symbolic link (symlink) and a regular file with the same name, the attacker can bypass security checks. The extract-zip utility incorrectly validates only the parent directory, enabling the attacker to write files to arbitrary locations on the system.
