## Description

The WP Data Access plugin for WordPress is vulnerable to Stored Cross-Site Scripting via text column values displayed in data entry form textarea fields in all versions up to, and including, 5.5.90, due to insufficient output escaping. The column value was echoed inside the textarea element with only ampersands encoded. This makes it possible for authenticated attackers, with contributor-level access and above, who can store unfiltered data in a text column (such as raw post meta values) that is opened in the plugin's data entry form, to inject arbitrary web scripts that execute whenever an administrator views or edits the affected record.
