CVE-2026-73326

CamaleonCMS contains a missing authorization vulnerability that allows any authenticated low-privileged user to access and modify plugin settings by reaching four unprotected plugin-administration endpoints without administrator-level authorization. Attackers can manipulate plugin configuration parameters at runtime across the attack, front_cache, cama_meta_tag, and cama_contact_form plugins to alter cached page behavior, modify public meta-tag output, or reconfigure contact forms, enabling account takeover when chained with stored cross-site scripting through the contact form's before_html field.

Summary		(es) CamaleonCMS contiene una vulnerabilidad de autorización faltante que permite a cualquier usuario autenticado con bajos privilegios acceder y modificar la configuración de plugins al acceder a cuatro puntos finales de administración de plugins desprotegidos sin autorización a nivel de administrador. Los atacantes pueden manipular los parámetros de configuración de plugins en tiempo de ejecución a través de los plugins attack, front_cache, cama_meta_tag y cama_contact_form para alterar el comportamiento de las páginas en caché, modificar la salida de metaetiquetas públicas o reconfigurar formularios de contacto, lo que permite la toma de control de cuentas cuando se encadena con cross-site scripting almacenado a través del campo before_html del formulario de contacto.
