MyBB Security Questions

Which versions, if any, of MyBB are practically impenetrable to exploits? I want to create a forum that is extremely secure.

Thanks!

I believe all are vulnerable. Just add multiple security measures for signups and into the actual form software, you may be able to atleast keep them away or get from them without being penetrated.

Sorry I was basically no help on this.

Changing the admin url on config files with for example example.com/admin
You make example.com/hgzpzazasvez

I always suggest you choose the latest version. however, you need to take some precautions. at this point you can write a message for help
