What are those?Especially as VB 4 has quite a few unpatched vulnerability.
Either you're out of date, speaking nonsenses or have found new exploits.Well if you did not know a few still do exist. I can confirm one XSS as I and my friend were the one to find it and report it on XDA. Ubuntu got hacked, XDA hacked most VB 4.XX forums are facing the heat. Its better to go VB5.
Totally agree, any software can be compromised if your install is a target. vB legacy products we're written and supported well, vB 5 is still a toddler and will improve with time. There are many communities still running vB 3.X and those community members would not have it any other way. the 4.X series is great for those "publishing" type of communities, I Personally I really like the 3.X version best with the only down side being not terribly mobile friendly without third party add ons and lack of spam control.Vbulletin is as secure as you make it. the main reason most of hacks commonly happen is due to flaws in the plugins and weak passwords. If you routinely take backups and make different passwords per social accounts you should be fine. I would say vb is worth the money if you think about the time, effort, dedication put into that.
