WordPress 3.8.2 is now available. This is an important security release for all previous versions and we strongly encourage you to update your sites immediately.

It also contains a fix to prevent a user with the Contributor role from improperly publishing posts. Reported by edik.
This release also fixes nine bugs and contains three other security hardening changes:
Pass along additional information when processing pingbacks to help hosts identify potentially abusive requests.
Fix a low-impact SQL injection by trusted users. Reported by Tom Adams of dxw.
Prevent possible cross-domain scripting through Plupload, the third-party library WordPress uses for uploading files. Reported by Szymon Gruszecki.
