## Description

The WP Data Access plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the autocomplete lookup field of data entry forms in all versions up to, and including, 5.5.89. The cause is insufficient output escaping: the lookup value read from the lookup table was echoed without escaping into a single-quoted HTML attribute. This makes it possible for unauthenticated attackers who can write data into a lookup table (for example through a public data entry form) to inject arbitrary web scripts that execute when a user opens a data entry form that uses the lookup.
