WordPress 2.6.2 has been released for download. This is an important security update for any WordPress sites that allow open registration. From the WordPress development blog:
With open registration enabled, it is possible in WordPress versions 2.6.1 and earlier to craft a username such that it will allow resetting another user’s password to a randomly generated password. The randomly generated password is not disclosed to the attacker, so this problem by itself is annoying but not a security exploit. However, this attack coupled with a weakness in the random number seeding in mt_rand() could be used to predict the randomly generated password.
This release also includes some other bug fixes outlined here.

that seems like a very strange security hole to me. Creating a username that resets the password of another user. wtf!?
It sure is creative. The big risk is when its coupled with the other flaw, allowing the attacker a shot at predicting the new password. That can lead to account compromise.
