Hi Sergey!
Yes, I know, we can switch off the patch(es) on our servers, but fortunately we
have customers and we have to answer their questions if they have. 😉
These tests covering the business logic, which is a good starting point for
what customers expect when installing the patches.

Hi!
Just for your information - if this is your own dedicated server and you do NOT
run untrusted code on it (which can potentially steal your data and send to
someone) - you can safely disable this patch.
Just because you do not defend yourself from yourself :)
Both vulnerabilities are LOCAL :)
