Description The plugin is vulnerable to Stored Cross-Site Scripting via the ‘xai_username’ parameter due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
