From WordPress:

We would like to announce that WordPress 1.5.1.3 is now released as we continue the availablity of a highly stable and extremely popular branch based on the 1.5 Strayhorn codebase. Development has moved on to some exciting new features for the next major release, but an important security issue was brought to our attention which required an update for our users. The problem is not yet public but you should update your blog as soon as possible to 1.5.1.3. If you are unable to do upgrade in the short-term you may protect yourself by deleting the xmlrpc.php file from your WordPress directory.

I haven’t upgraded yet, still using 1.5. I am waiting on my hosting company to advise if this is something they are going to do for me or if I have to do it myself.
