      "value": "Vvveb before 1.0.8.2 contains an unauthenticated reflected cross-site scripting vulnerability in the visual editor preview renderer that allows attackers to execute arbitrary JavaScript by manipulating the r query parameter and _component_ajax POST parameter. Attackers can craft a malicious link or auto-submitted form that causes victims to execute attacker-controlled JavaScript in the context of the Vvveb origin, as the gating function isEditor() performs no session, role, or token verification and the view handler injects raw HTML POST body content without sanitization."

      "value": "Vvveb antes de 1.0.8.2 contiene una vulnerabilidad de cross-site scripting reflejado no autenticado en el renderizador de vista previa del editor visual que permite a los atacantes ejecutar JavaScript arbitrario manipulando el parámetro de consulta r y el parámetro POST _component_ajax. Los atacantes pueden crear un enlace malicioso o un formulario autoenviado que hace que las víctimas ejecuten JavaScript controlado por el atacante en el contexto del origen de Vvveb, ya que la función de control isEditor() no realiza ninguna verificación de sesión, rol o token y el gestor de vistas inyecta contenido HTML POST sin sanitización."
