Official description
The User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'usp_access' shortcode in all versions up to, and including, 20260110 due to insufficient input sanitization and output escaping on user supplied attributes.
