WordPress 3.1.2 is now available. This release addresses a vulnerability that allowed contributor-level users to improperly publish posts. It also fixes several non-security related issues that were missed in version 3.1.1.
It’s important to update from any version to 3.1.2 as soon as possible, especially on blogs where users can register as contributors.
