Matt,

It looks like somebody opened up this CVE and never notified us.

It also looks like this report is bogus, but I just heard about it in
the last few minutes and I'd like to check it out before I say more.

I've already heard from one big customer asking about it, as they gave
it a CVSS3 score of 9.8, which seems insane and irresponsible.

Not the sort of thing I want to see at 0345 when I'm about to fall asleep.

H

PS - I'm not sending this encrypted because our PGP key has expired and
Brad hasn't had time to refresh that yet.  I've asked him if he can get
that done sometime "today".

Hi Marius,

Nobody told us about this one.

I'm not certain yet, but this seems completely bogus to me.

I'll loop in some wizards and see what I can find.
