The advisory
The WP Data Access – App Builder for Tables, Forms, Dashboards, Charts & Maps plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.5.88 via the 'rel_tab' parameter. This makes it possible for unauthenticated attackers to extract every row and column of the underlying database table backing any anonymously published app, including WordPress user password hashes, email addresses, and password-reset keys from wp_users. Exploitation requires that an administrator has published at least one app with its REST API authorization set to 'anonymous', which is the standard configuration for publicly embedded apps.
