CVE-2017-7200: SSRF
An SSRF issue was discovered in OpenStack Glance before Newton. The 'copyfrom' feature in the Image Service API v1 allowed an attacker to perform masked network port scans. With v1, it is possible to create images with a URL such as 'http://localhost:22'. This could then allow an attacker to enumerate internal network details while appearing masked, since the scan would appear to originate from the Glance Image service.
