Comment 5 Vojtech Juranek 2018-12-04 13:16:48 UTC

We tried to come up with a general blacklist which won't break any existing setup. However, it turned out that such blacklist has to be very less restrictive than we originally expected, so it probably won't (fully) solve this issue or any of the related issues. Main purpose of proposed patch is to add documentation so that admins can easily adjust blacklists to their needs according to their specific setups.

We cannot fix this for 4.2.8 according to comment #5, closing.
