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. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
