The Joomla! Team has reported a security hole in Joomla! 1.5.0, caused by the same XML-RPC protocol security problem that has been solved in Wordpress by the new release, WP 2.3.3.

The problem regards every Joomla! site that uses the Blogger API XML-RPC plugin, disabled by default.

While waiting for Joomla! 1.5.1, those worried by this high risk security hole can disable the Blogger API XML-RPC plugin.
