[URGENT!] Exploit can crash servers at free will. (Again)

Similarly to this post: [URGENT!] Players can crash all players at free will in an experience, and the server as well - #4 by bewarethepaws

Players are able to crash both the server and every client inside a roblox server instance. The reason behind the crash is unknown. The app just closes without giving any errors.

I have uploaded a crash log to the message.

Have been experiencing this HEAPS with my own game. Thought it was something to do with layered clothing and tools but it seems not?

Didn’t see your previous post as it was unlisted, probably so bad actors didn’t find out about it.

Could also be related:

Do you have any repro steps? Any surrounding info at all? Could it be similar to the previous vulnerability, maybe a loophole to the patch they applied to it? If you have any further info I’d appreciate a DM to look into it myself.

No repro steps at all, couldn’t find any information about it online.

Last time, players were able to run an animation to crash users ingame, here’s the GitHub repo for that: GitHub - 0zBug/Crash: John Crash

This could be totally different, in the crash log it says
[FLog::Output] Session Transition FSM: Error Occurred.

But only the moderators will be able to see the rest of the file.
Also thank you for posting that thread, I was searching for it.
