WP Data Access WordPress plugin vulnerabilities

The WP Data Access WordPress plugin before 5.5.84 does not restrict its database table export action to authorized users, gating it only with a token that the plugin itself prints into the public pages on which it displays a table. This allows unauthenticated attackers to export the complete contents of any publicly displayed table, including columns and rows withheld from the display shown to visitors.

The WP Data Access WordPress plugin before 5.5.77 does not correctly check authorization on one of its application REST endpoints, verifying only read permission before performing a write. This allows unauthenticated attackers to modify data in an application exposed for anonymous read access even when update actions have been disabled by the administrator.

The WP Data Access WordPress plugin before version 5.5.79 does not validate the column names it accepts on one of its unauthenticated AJAX actions, and the nonce guarding that action does not cover them, allowing unauthenticated attackers to read arbitrary columns of the database table the affected front-end form is bound to, including user password hashes where that table is the users table.
