CVE-2026-46485

Dashy is a self-hostable personal dashboard. Prior to 4.0.8, Dashy deployments using OIDC can allow unauthenticated users or non-admin authenticated users to write changes to the main config.yaml through the config-saving functionality despite configured permissions, allowing unauthorized modification of dashboard configuration and potential service disruption. This issue is fixed in version 4.0.8.

Summary		(es) Dashy es un panel personal autoalojable. Antes de la versión 4.0.8, las implementaciones de Dashy que utilizan OIDC pueden permitir a usuarios no autenticados o a usuarios autenticados no administradores escribir cambios en el archivo principal config.yaml a través de la funcionalidad de guardado de configuración, a pesar de los permisos configurados, lo que permite la modificación no autorizada de la configuración del panel y una posible interrupción del servicio. Este problema se ha solucionado en la versión 4.0.8.
