FKIE_CVE-2026-9809

Vulnerability from fkie_nvd - Published: 2026-05-29 12:16 - Updated: 2026-07-21 12:10
Severity
7.6 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:H/A:N
Summary
A stored Cross-Site Scripting (XSS) vulnerability exists in the Projects component of Mautic 7. When displaying project tags and popovers on administrative detail views (such as campaigns, emails, or forms), user-supplied project names are rendered without proper sanitization. An authenticated user with permissions to create or edit projects can exploit this to inject malicious script payloads. When an administrative user views an entity associated with a compromised project and hovers over its tag, the injected script executes within the context of their active browser session. This could allow an attacker to perform administrative actions on behalf of the victim, alter system configurations, or exfiltrate sensitive data.

      "value": "Una vulnerabilidad de cross-site scripting (XSS) almacenado existe en el componente Proyectos de Mautic 7. Al mostrar etiquetas de proyecto y popovers en vistas de detalle administrativas (como campa\u00f1as, correos electr\u00f3nicos o formularios), los nombres de proyecto proporcionados por el usuario se renderizan sin la sanitizaci\u00f3n adecuada. Un usuario autenticado con permisos para crear o editar proyectos puede explotar esto para inyectar cargas \u00fatiles de script maliciosas. Cuando un usuario administrativo ve una entidad asociada con un proyecto comprometido y pasa el cursor sobre su etiqueta, el script inyectado se ejecuta dentro del contexto de su sesi\u00f3n de navegador activa. Esto podr\u00eda permitir a un atacante realizar acciones administrativas en nombre de la v\u00edctima, alterar configuraciones del sistema o exfiltrar datos sensibles."
