Yesterday WordPress announced the release of WordPress 3.0.2, their 2nd major update to the groundbreaking WordPress 3.0.
The biggest update on this release was addressing the problem where an author level user could gain further access to your site. The following problems were also fixed:
- emove pingback/trackback blogroll whitelisting feature as it can easily be abused.
- Fix canonical redirection for permalinks containing %category% with nested categories and paging.
- Fix occasional irrelevant error messages on plugin activation.
- Minor XSS fixes in request_filesystem_credentials() and when deleting a plugin.
- Clarify the license in the readme
- Multisite: Fix the delete_user meta capability
- Multisite: Force current_user_can_for_blog() to run map_meta_cap() even for super admins
- Multisite: Fix ms-files.php content type headers when requesting a URL with a query string
- Multisite: Fix the usage of the SUBDOMAIN_INSTALL constant for upgraded WordPress MU installs
The author level security issue could be quite a big problem so I recommend you all update to 3.0.2 through your admin area or via FTP when you have time.
