Summary
Typemill CMS 2.x Persistent XSS via Markdown javascript URI
Details

Typemill CMS version 2.x contains a persistent cross-site scripting vulnerability in the Markdown parser extension that allows authenticated users with theme-configuration access to inject malicious JavaScript URIs by supplying unsanitized href values in Markdown links. Attackers can craft Markdown links using the javascript: scheme through ParsedownExtension.php or TwigMarkdownExtension.php, storing a persistent payload that executes in the browser of every visitor who clicks the link, enabling session cookie theft, authenticated request forgery, and credential harvesting.
