User::setDonationLink() (objects\/user.php) stores the value and save() validates it only with filter_var(&#8230;, FILTER_VALIDATE_URL), which accepts strings such as http:\/\/evil.example\/&#8221;onmouseover=alert(document.domain)\/\/, while getDonationLink() applies only strip_tags() and does not encode double quotes. plugin\/CustomizeUser\/actionButton.php echoes the value unencoded into an <a href=\"...\"> attribute, and that button is included from view\/modeYoutubeBottom.php on the watch page when the CustomizeUser option allowDonationLink is enabled. An authenticated user who updates their own profile via objects\/userUpdate.json.php can therefore break out of the href attribute and inject an event handler that executes JavaScript in the browser of any visitor\u2014including an administrator\u2014who views the attacker&#8217;s videos and interacts with (for example, hovers over) the donation button.
