      "value": "ChurchCRM is an open-source church management system. Prior to 6.5.3, a stored Cross-Site Scripting (XSS) vulnerability in ChurchCRM's Note Editor allows authenticated users with note-adding permissions to execute arbitrary JavaScript code in the context of other users' browsers, including administrators. This can lead to session hijacking, privilege escalation, and unauthorized access to sensitive church member data. This vulnerability is fixed in 6.5.3."

      "value": "ChurchCRM es un sistema de gestión de iglesias de código abierto. Antes de la versión 6.5.3, una vulnerabilidad de cross-site scripting (XSS) almacenado en el Editor de Notas de ChurchCRM permite a usuarios autenticados con permisos para añadir notas ejecutar código JavaScript arbitrario en el contexto de los navegadores de otros usuarios, incluidos los administradores. Esto puede llevar a secuestro de sesión, escalada de privilegios y acceso no autorizado a datos sensibles de miembros de la iglesia. Esta vulnerabilidad está corregida en la versión 6.5.3."
