October is a Content Management System (CMS) and web platform. Prior to versions 3.7.13 and 4.0.12, a cross-site scripting (XSS) vulnerability was identified in October CMS backend configuration forms. A user with the Global Editor Settings permission could inject malicious HTML/JS into the stylesheet input at Markup Styles. A specially crafted input could break out of the intended <style> context, allowing arbitrary script execution across backend pages for all users. This issue has been patched in versions 3.7.13 and 4.0.12.
