Affects any version since Windows 10 Edition is out.
On Pocket Edition the used items are sendt, and the slot positions in the crafting table/inventory, only the result.
The windows 10 edition sends an empty array. This way there is no way to detect wether oak or acacia wood was used to craft a sign as example. Effects every item/block that can be crafted out of different blocks.
Examples: Signs, chests, torches (which coal type), tnt (which sand type) etc.

Not with my new anti-cheat system in Genisys 😛
Technically speaking, the real bug is that Win10 doesn't tell a server what's in the crafting grid. (https://bugs.mojang.com/browse/MCPE-16366)
The packet input field tells the server what to take from the player's inventory. Since in Win10 the items are already gone from your inventory, this is not technically a bug. The recipe UUID will also tell you what materials have been used (provided the correct UUID is sent).

Windows 10 Edition drops the air in the crafting grid.

This is a bulk resolve of issues that haven't been updated to 0.16.0+ yet. Please comment below (To open the ticket) and update your affected versions. If you cannot reproduce the bug, please write in the comments so we can resolve it as "Cannot Reproduce". Thank You!

Should be closed and discussed in https://bugs.mojang.com/browse/MCPE-16366
CRITICAL! Players with windows 10 edition can easily cheat items on LAN and/or get kicked/timeouted from the LAN game
