Sunil Yadav from IBM Security Services reported a persistent XSS in
Horizon. An authenticated user may conduct a persistent XSS attack by
setting a malicious metadata to a Glance image, a Nova flavor or a
Host Aggregate and tricking an administrator to load the update
metadata page. Once executed in a legitimate context this attack may
result in a privilege escalation. All Horizon setups are affected.
