The filename route parameter is joined into a filesystem path without traversal/boundary validation, allowing file reads outside data/uploads/app-icons/. This vulnerability is fixed in 1.22.0."

Antes de 1.22.0, existe una vulnerabilidad de salto de ruta no autenticado en /api/app-icons/[filename]. El parámetro de ruta filename se une a una ruta del sistema de archivos sin validación de salto/límite, lo que permite la lectura de archivos fuera de data/uploads/app-icons/. Esta vulnerabilidad está corregida en 1.22.0."
