WordPress team has released WordPress 2.8.5 today as a hardening release to make WordPress extra secure. Because the update improves your site security, it is recommended that you upgrade as soon as possible.
Yesterday, WPBeginner was facing some hacker attack. It was users trying to reset the password, but thankfully they could not get the random password because the site is not using the default admin user. But nonetheless it was an annoying thing to deal with. Hackers kept trying to reset our password and we had to deal with it for six times until we added more security layers.
WordPress has released another security release as version 2.8.3. This version fixed problems that were left in 2.8.2 so upgrade now. This is a security release so the upgrade should not be optional.
Not long ago WordPress released its version 2.8.1, but there has been another update. WordPress 2.8.2 was released today as a security patch to fix the possible exploit.
WordPress 2.8.1 fixes many bugs and improves security for plugin administration pages. In the previous version, admin pages added by certain plugins could be viewed by unprivileged users, resulting in information being leaked. Not all plugins are vulnerable to this problem, but WordPress staff and WPBeginner advise you to upgrade to 2.8.1 to be safe.
