      "value": "An improper access control vulnerability exists in janeczku/calibre-web. The affected version allows users without public shelf permissions to create public shelves. The vulnerability is due to the `create_shelf` method in `shelf.py` not verifying if the user has the necessary permissions to create a public shelf. This issue can lead to unauthorized actions being performed by users."

La versi\u00f3n afectada permite a los usuarios sin permisos de estanter\u00eda p\u00fablica crear estanter\u00edas p\u00fablicas. La vulnerabilidad se debe a que el m\u00e9todo `create_shelf` en `shelf.py` no verifica si el usuario tiene los permisos necesarios para crear una estanter\u00eda p\u00fablica. Este problema puede provocar que los usuarios realicen acciones no autorizadas."
