Unauthenticated administrator escalation via arbitrary user-meta write

Published Jul 10, 2023 · Updated Nov 8, 2024

Privilege escalation in tagDiv Cloud Library before 2.7 allows remote attackers to grant a WordPress account administrator rights. The tdb_user_form_on_submit AJAX action accepts unauthenticated formElements input and writes arbitrary user-meta keys, including wp_capabilities. No WordPress login is required; knowledge of a target user ID and access to admin-ajax.php suffice to obtain administrator control.
