Summary
The WP Data Access plugin for WordPress by peterschulznl is affected up to and including 5.5.89. Missing sanitization and escaping (CWE-79) in its Image URL column renderer lets an authenticated attacker with subscriber-level access or above store scripts that run when a user opens the page. Exploitation requires an administrator to publish a DataTables shortcode over an attacker-controlled column with the Image URL media type.

Description from the CNA
The WP Data Access – App Builder for Tables, Forms, Dashboards, Charts & Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ImageURL column value (populated from wp_usermeta.description in the demonstrated path)' parameter in all versions up to, and including, 5.5.89 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires an administrator to have published a DataTables shortcode over a database column the attacker controls (e.g., wp_usermeta.description) with the Image URL media type assigned to that column — both are supported plugin features but are not enabled by default.
