      "value": "CI4MS is a CodeIgniter 4-based content management system skeleton. Prior to version 0.31.9.0, the `Pages` backend module registers the `html_purify` validation rule on language-keyed page content but persists the raw, un-purified POST value into the database. The public renderer for pages (`Home::index()` → `app/Views/templates/default/pages.php`) emits `$pageInfo->content` without `esc()`, yielding stored XSS that fires for every public visitor of the affected page — including administrators. Because pages may be promoted to the site home page, the payload can be served at `/` and reach every visitor of the site. Version 0.31.9.0 patches the issue."

      "value": "CI4MS es un esqueleto de sistema de gestión de contenido basado en CodeIgniter 4. Antes de la versión 0.31.9.0, el módulo de backend ’Pages’ registra la regla de validación ’html_purify’ en el contenido de la página con clave de idioma, pero persiste el valor POST sin procesar y sin purificar en la base de datos. El renderizador público para páginas (’Home::index()’ ? ’app/Views/templates/default/pages.php’) emite ’$pageInfo  ->  content’ sin ’esc()’, produciendo XSS almacenado que se activa para cada visitante público de la página afectada - incluidos los administradores. Debido a que las páginas pueden ser promovidas a la página de inicio del sitio, la carga útil puede ser servida en ’/’ y alcanzar a cada visitante del sitio. La versión 0.31.9.0 corrige el problema."
