CVE-2021-24172Network attack vector

Database disclosure via forged backup request

Published Apr 5, 2021 · Updated Aug 3, 2024

Cross-site request forgery in Vinmatrix VM Backups 1.0 allows remote attackers to generate site backups through a logged-in user's browser. The backup action accepts forged requests without a CSRF check, writes database, plugin, and theme archives under uploads without access restrictions, and can send them to an attacker-chosen email address. Exploitation requires a logged-in user and a WordPress host running PHP before 7; successful use exposes backup contents.
