Joomla has just released back-to-back “critical security releases” after it just released Joomla 3.4.6. Make of that what you will. They’ve just released a version that addresses a “severe security concern”, which is available immediately.
The patch apparently closes a security hole the size of the Mariana Trench which made it “really, really easy” to hack your Joomla sites. Now that the news is out in the wild, it’s of the upmost importance to patch your site before the bad guys start poking around.
So, ladies and gentlemen, it’s time to start updating all your sites – again – using your prefered method (the built-in updater, MyJoomla or a manual update) to make sure your sites are good to go.
May the force be with you, and don’t forget to make a back-up before you update.
