CVE-2026-19693

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.

This is an Important arbitrary file write vulnerability in the extract-zip utility. The flaw arises from insufficient validation of archive entries, allowing a remote attacker to write files to arbitrary locations on the system by providing a specially crafted zip archive. This requires user interaction to extract the malicious archive, but successful exploitation could lead to significant system integrity and availability compromise.
