Description Martin Prpič 2016-09-12 09:48:43 UTC 
The following flaw was reported in OpenStack's manila-ui:

It was discovered that the Metadata field in the "Create Share" form allows users to inject malicious HTML/JavaScript code that will be reflected in the "Shares" overview. The issue comes from a mark_safe() call on the user supplied metadata.
