      "value": "The Open edx Enterprise Service app provides enterprise features to the Open edX platform. From 7.0.2 to 7.0.4, the sync_provider_data endpoint in SAMLProviderDataViewSet fetches SAML metadata from a URL stored in SAMLProviderConfig.metadata_source. An authenticated user with the Enterprise Admin role can set this field to an arbitrary URL via the SAMLProviderConfigViewSet PATCH endpoint, then trigger a server-side HTTP request by calling sync_provider_data. The fetch in fetch_metadata_xml() passes the URL directly to requests.get() with no scheme enforcement, IP filtering, or timeout. This vulnerability is fixed in 7.0.5."

      "value": "La aplicación Open edx Enterprise Service proporciona funcionalidades empresariales a la plataforma Open edX. Desde la versión 7.0.2 hasta la 7.0.4, el endpoint sync_provider_data en SAMLProviderDataViewSet obtiene metadatos SAML de una URL almacenada en SAMLProviderConfig.metadata_source. Un usuario autenticado con el rol de Administrador Empresarial puede establecer este campo a una URL arbitraria a través del endpoint PATCH de SAMLProviderConfigViewSet, y luego activar una solicitud HTTP del lado del servidor al llamar a sync_provider_data. La obtención en fetch_metadata_xml() pasa la URL directamente a requests.get() sin aplicación de esquema, filtrado de IP ni tiempo de espera. Esta vulnerabilidad se corrige en la versión 7.0.5."
