      "value": "CamaleonCMS contains a stored cross-site scripting vulnerability that allows authenticated low-privileged users to execute arbitrary JavaScript in an administrator's browser by injecting unsanitized HTML payloads into the post title parameter during draft creation. Attackers can submit a malicious HTML payload as a draft title through the drafts creation endpoint, which is persisted to the database without escaping and later rendered as raw HTML in the admin drafts listing, enabling administrator session compromise, cookie theft, and forged authenticated requests."

      "value": "CamaleonCMS contiene una vulnerabilidad de cross-site scripting almacenada que permite a usuarios autenticados con bajos privilegios ejecutar JavaScript arbitrario en el navegador de un administrador inyectando cargas útiles HTML no saneadas en el parámetro del título de la publicación durante la creación de borradores. Los atacantes pueden enviar una carga útil HTML maliciosa como título de borrador a través del endpoint de creación de borradores, que se persiste en la base de datos sin escapar y luego se renderiza como HTML sin procesar en el listado de borradores del administrador, lo que permite el compromiso de la sesión del administrador, el robo de cookies y solicitudes autenticadas forjadas."
