## Technical details

The vulnerability is a stored XSS in the channel About field (feed/index.php) where the feedHtmlDescription() filter fails to sanitize unquoted event-handler payloads. The payload persists and executes in the browser when the RSS feed is rendered via rss-style.xsl with disable-output-escaping enabled, affecting any visitor including administrators. A registered user can trigger this by editing their own channel's About text.
