From 0.10.0 until 6.54.1, a Server-Side Request Forgery in Ghost Admin image fetching allowed any staff-level user to perform a blind HTTP GET request against internal hosts. No output was returned, but this could have been used to probe open ports on internal hosts. This issue is fixed in version 6.54.1."

Desde 0.10.0 hasta 6.54.1, una falsificación de petición del lado del servidor en la obtención de imágenes de Ghost Admin permitía a cualquier usuario con nivel de personal realizar una petición HTTP GET ciega contra hosts internos. No se devolvía ninguna salida, pero esto podría haberse utilizado para sondear puertos abiertos en hosts internos. Este problema está solucionado en la versión 6.54.1."
