CVE-2026-9811

Estado: AplazadaMedia (5.4)—

A stored Cross-Site Scripting (XSS) vulnerability exists in the project selector component of Mautic 7. When rendering selection menus for associating projects with system entities, the application fails to sanitize project names returned via AJAX before injecting them into the DOM as option fields. An authenticated user with permissions to create projects can exploit this to store a malicious script payload in the project's name. When another administrative user subsequently opens an entity editor containing the project selector, the injected script executes within the context of their active browser session. This could allow an attacker to hijack the session, perform unauthorized state coordination, or access organizational data within the dashboard.

Al renderizar menús de selección para asociar proyectos con entidades del sistema, la aplicación no sanitiza los nombres de proyectos devueltos vía AJAX antes de inyectarlos en el DOM como campos de opción. Un usuario autenticado con permisos para crear proyectos puede explotar esto para almacenar una carga útil de script malicioso en el nombre del proyecto. Cuando otro usuario administrativo posteriormente abre un editor de entidades que contiene el selector de proyectos, el script inyectado se ejecuta dentro del contexto de su sesión de navegador activa.
