WordPress 2.8.4 has been released. It is highly reccommended that you upgrade your WordPress blog or website as soon as possible, as this release addresses security and stability issues. Matt released this note explaining the release:
Yesterday a vulnerability was discovered: a specially crafted URL could be requested that would allow an attacker to bypass a security check to verify a user requested a password reset. As a result, the first account without a key in the database (usually the admin account) would have its password reset and a new password would be emailed to the account owner. This doesn’t allow remote access, but it is very annoying.
We fixed this problem last night and have been testing the fixes and looking for other problems since then. Version 2.8.4 which fixes all known problems is now available for download and is highly recommended for all users of WordPress.
dazil hosting clients can upgrade via their WordPress admin panel, or contact us if you require assistance.
