What the vulnerability does
The Simple User Registration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpr_admin_msg' parameter in all versions up to, and including, 6.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The vulnerability can be exploited remotely without authentication or user interaction. An attacker can inject code that executes in other users' browsers, potentially stealing session data or performing actions on their behalf.
