"Please don't download any of my games. There is a security exploit found with Unity applications. I can't draft this page since I don't know if making it public later could cause problem to existing customers."

It is not just CB, the security vulnerability is present in basically all Unity games and applications published in the last 8 years. No know malware uses it but better safe than sorry.

Unity software either needs to be rebuilt from source with patched versions of the editor or already built applications can be patched by a special patching tool Unity has released.
