Any possible command can be executed by right-clicking on the printed NBT changed sign.

Description

(I'm sorry I don't have a Discard.)

I found a bug which can run command in the server.

Steps to reproduce:

Save an schematic which has an sign.

Then edit the NBT of the sign. (Causes the sign to run the command when clicked.)

After that, print it.

You can print out the bill of materials first to see if it contains a sign.
(I re-recorded the video for this reason.)

Finally, right-click on the sign.

The video can be viewed at the link below.

The changes to the NBT of the sign are shown below.

In addition, I found that the server does not record the corresponding logs when the command is run, and the server administrator does not receive the relevant information. (doubtful)

I can't provide the logs for this reason, and I'm sorry for that.

Commands executed in this way must not be too long, otherwise the contents of the sign will be lost after printing.
This length is much smaller than what can be entered in the console, so much so that the give command's enchantment-related NBT can't be placed.

Game Log

I'm sorry that I can't provide logs because this bug doesn't generate logs.

[IThundxr]

Please try reproducing this on 0.5.1.h

[Qiong-Mengzi]

Looks like it's been fixed in the next release.

Sorry for the delay.

Then I found another bug where all the text of the hanging sign was missing after printing...

(It's just just discovered, and then open an new issue after verification)
