CVE-2026-113594
Sharkord anterior a la 0.0.8 contiene una vulnerabilidad de falta de autorización que permite a cualquier miembro autenticado cambiar la configuración de todo el servidor mediante la llamada a la mutación tRPC others.updateSettings sin disponer del permiso MANAGE_SETTINGS. Los atacantes pueden establecer una contraseña de acceso, desactivar el registro, poner a cero los límites de subida o activar o desactivar la carga de plugins para provocar una denegación de servicio a otros miembros.
