Hi, does Minecraft 1.21.9 snapshot 25w09a has any vulnerability?

What do you mean

can you provide context as to what makes you ask this to begin with please

I'm suspicious of why somebody would want to know of a clientside vulnerability, here

Your answer is that I don't know of anything but also that even if I did I would say this exact same thing because disclosing client vulns publicly would be deeply stupid

And even if it is a thing and someone else here knows about it nobody else here is going to tell you anything

locking and closing this as it’s weird and suspicious as everyone else agrees.
dont ask around for this ty
