Forgot the reference, here's the exact code:

[Salvatore, thanks for forwarding it]

Some other notes:


This is a directory traversal issue that requires authentication, but
there doesn't seem to be a CSRF protection in place (unless I'm
missing something).
The (stored) XSS part of it is not entirely fixed for the case where
an attacker successfully took advantage of it since the sanitation is
only performed when storing to the .json file.

The other operations related to views (in views_view.php) are all
still vulnerable to XSS via the view_name GET parameter.

The authentication cookie uses a persistent token for every user (no
session ids or any sort of nonce), which is an issue on its own, but
it also doesn't verify that the group stored in the cookie actually
corresponds to the user. As of 3.5.7 the groups feature still doesn't
seem to be in use, however.

So I guess we are going to need at least one more CVE id for the
remaining XSS issues in views_view.php and I leave the rest up to the
opinion of others (upstream included).
