Massive item spawning glitch

Describe
There is a bug where you can use a book and quill, plus nbt block and reader and shulker box to spawn in literally any item, I'm not exactly sure on how to do it, because I only saw this from players on a server I'm playing on
Steps to reproduce
Put nbt in a book, put book in chest, point nbt reader to chest, use some program (probably just writing the data to the nbt block) then break the nbt storage block and then open the shulker then you have any item
Multiplayer?
Yes
Version
1.18.2-0.7.31r (Latest 1.18.2)
Minecraft, Forge and maybe other related mods versions
40.2.17 Minecraft 1.18.2

No response
okay you don't need the shulker box, the nbt storage block just turns into it
Would it be possible for you to get that script he used?
It's a bit hard to guess how it works
Well the admin who discovered it, deleted the script, the server admins and I are gonna try to recreate it, it looks simple enough, but could also be pretty complex, I'll get back to you
One workaround for now is that you can disable the nbt storage in the config until I find a solution
Greetings again
The rat texted me per discord
but I can assure you that it's not caused by your mod alone
My thought is now, that the NBT data from the NBT storage gets injected into the shulker he collects when he breaks the nbt storage. So I would need to know what the pickaxe does/the enchantments from it, so find a potential fix
But my guess is that I can't fix it but the author of the mod of the enchantment/pickaxe needs to fix this. The NBT Storage seems to be just a medium for the NBT data to move to the shulker box.
It must either be something on the pickaxe (an enchantment maybe) or some other mod that modifies the block breaking.. Also, about the book, the screenshots only show page 2 and 3, what's up with page 1? Is it empty? And are you sure it is empty and there are no invisible characters hidden in it?

Pickaxe from what i know is a normal pickaxe and as for the book the first page is empty yes. Just checked it myself and there's no invisible characters.

Would it be possible to get the modlist?
You should probably not listen to t8rt0t by the way. He doesn't want us (the admins of that server) knowing how the bug exactly works.
also the block turns INTO a shulker box, im 99% sure its not caused by any other mod

We think it's some kind of NBT injection. We don't modify the loot table at all, it's just a basic static loot table
So our theory is, that some kind of enchantment, belt, ring or whatever turns the block into the shulker box and puts the dropped block into the shulker itself while injecting the NBT data of the NBT storage into the shulker which creates the item

Yes, I take this with a grain of salt
Would you mind placing the book in a chest and give us the output of /data get block with the coordinates of said chest?

Wild guess, but because of apotheosis mentioned, can it be, that it is a small bug inside apotheosis special item spawn system?

Doubt it honestly
But honestly, there are 2 villagers in the dirt house, together with a lectern and his pickaxe is shiny. There must be an enchantment on it.
Pickaxe from what i know is a normal pickaxe and as for the book the first page is empty yes. Just checked it myself and there's no invisible characters.
I can see in the video that the pickaxe is shiny
But I guess the pickaxe does not exist anymore?
Sadly no. A different admin acted too fast and just /clear'd them but yes the pickaxe is enchanted I just misworded my sentence but even then theres no enchantments in the pack that could cause this.
Would you be able to send a zip of the pack or a curseforge profile file to me, would like to do some testing in your pack.

I tried a few things now but I can't manage to reproduce it. As far as I can see it must either be the script or some cross mod interaction. The latter would make more sense since the player also mentioned that "he can assure you that it's not caused by your mod alone".
If you want to cross out the script part entirely, assuming that he really used a script saved on the pc and didn't just type it into the lua console, you could check the server files for the script. It should be in world/computercraft/computer/ but you'd have to guess the id, which could be pretty difficult if a lot of people on the server use CC:Tweaked.
If the pc still exists in the world, you could also just CTRL+Middle Mouse Button it in Creative or just break it in survival and check the tooltip for the id.
okay so obviously we all know they made the nbt storage think it's a shulker somehow
what I think they did is somehow add shulker box nbt to the nbt storage block, and the nbt reader is just a extra thing so they don't need to type it in all the time
probably pretty obvious too, but I can't really test that theory right now
If the pc still exists in the world, you could also just CTRL+Middle Mouse Button it in Creative or just break it in survival and check the tooltip for the id.
The PC was destroyed by the Admin I mentioned before I could peek inside sadly.
The files might still be inside the world folder, but as I said, it might be difficult to guess the ID of the pc

Checked all the PCs in the world folder and found nothing.
Then it must be a easy copy-pasta commands, people can compress any Lua code to a single line
Well they 100% did because another group in the server trapped them in the end
Depends on if the admin/s deleted the code manually or just broke the computer, if second, its a copy paste command

Computer was exploded so yes It's the second one.
Thank you both for your feedback
Sorry for taking your guys' time.
Don't worry, happens to the best
For the next time, I would recommend to look through a datapack before installing it (;
nevermind we figured it out, he snuck a data pack into the server disguised as recipes for another mod
