CVE-2026-121536 WP Data Access <= 5.5.90 - Authenticated (Subscriber+) SQL Injection via 'engine' Parameter
Description
The WP Data Access – App Builder for Tables, Forms, Dashboards, Charts & Maps plugin for WordPress is vulnerable to generic SQL Injection via the 'engine' parameter in all versions up to, and including, 5.5.90 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is only exploitable when an administrator has configured a Data Project page to admit a lower-privileged role, which is the plugin's documented mechanism for sharing projects with subscribers and other users.
