XSS in noVNC
Status in OpenStack Dashboard (Horizon):

Status in OpenStack Security Advisory:

Bug description:
I recently reported an XSS bug in noVNC, which has since been fixed in
0.6.2: https://github.com/novnc/noVNC/issues/748.
Depending on how OpenStack pulls in the noVNC viewer, it might be
worth a security note or release.
Vulnerability Summary:
It's possible to set up a malicious noVNC server, then send someone a
URL like http://GOOD_NOVNC/vnc_auto.html?host=BAD_NOVNC. The good noVNC
will use a WebSocket to connect to the malicious one, then display a
status message that runs JavaScript in the user's browser.
