OVERVIEW

        WordPress 2.8.4 has been released fixing a vulnerability.


IMPACT

        Through the use of a specially crafted URL, this vulnerability could 
        allow an attacker to bypass a security check when verifying a user 
        requested password reset. This resulted in the "...first account 
        without a key in the database (usually the admin account)..." having
        its password reset and emailed to the owner of the account. [1]


MITIGATION

        The vendor recommends upgrading to the latest version of WordPress. [1]
