Technical details
The vulnerability is a stored XSS in the permalink parameter due to insufficient input sanitization and output escaping. The parameter is processed through sanitize_url() which does not prevent fetching attacker-controlled remote URLs, and the response body including script tags and event handlers is written directly to disk via file_put_contents(). An authenticated attacker with subscriber-level access can exploit this by supplying a URL pointing to attacker-controlled content containing scripts that will be persistently stored and executed in the context of the application.
