Furthermore for fetching from http/https addresses there is currently no allowlist on the URI scheme, no host check, no IP-range restriction, and no protection against pointing the URI at internal or link-local addresses.This issue affects Apache Flink Kubernetes Operator: from 1.3.0 before 1.15.0.\n\nUsers are recommended to upgrade to version 1.15.0, which fixes the issue."

Esto permite a un usuario con permisos de creación de CR leer archivos del sistema de archivos del pod del operador y extraer contenido de cualquier almacén de respaldo accesible a través de la capa de sistema de archivos conectable de Flink y acceder a ellos a través del trabajo Flink enviado. Además, para la obtención desde direcciones HTTP/HTTPS, actualmente no hay una lista de permitidos para el esquema URI, ninguna comprobación de host, ninguna restricción de rango IP y ninguna protección contra el direccionamiento del URI a direcciones internas o de enlace local. Este problema afecta a Apache Flink Kubernetes Operator: desde 1.3.0 antes de 1.15.0.\n\nSe recomienda a los usuarios actualizar a la versión 1.15.0, que corrige el problema."
