Technical details
This is a stored cross-site scripting (XSS) vulnerability in the AD_Server plugin's log.php endpoint. The vulnerability occurs because user input from the `label` parameter is copied directly into the database without sanitization via xss_esc(). When administrators view the Ad Types report, this stored payload is rendered using jQuery's .html() method, which interprets and executes the injected HTML and JavaScript. No authentication is required to send the malicious request, only a same-origin Referer header (satisfied by normal browser behavior). The attacker's JavaScript runs in the administrator's browser session with full access to the site origin, enabling account takeover and site compromise. As of the advisory date, no patch was available.
