This site has been upgraded to WordPress 2.2.3. This is a security and bug fix that addresses several issues in WordPress 2.2.2. There are two high priority updates in this release:
- Invalid RSS2 Comments Feed
Version 2.2.2. My comments RSS2 feed was invalid because the author tags did not enclose a valid email address. - Users without unfiltered_html capability can post arbitrary html
The user only needs to tamper data sent to post.php or page.php and add a field named no_filter with any value.
