We also fixed three other security issues:
We also made four hardening changes, discovered by J.D. Grimes, Divyesh Prajapati,Allan Collins and Marc-Alexandre Montpas.
Download WordPress 4.1.2 or venture over to Dashboard ? Updates and simply click “Update Now.” Sites that support automatic background updates are already beginning to update to WordPress 4.1.2.
A number of plugins also released security fixes yesterday. Keep everything updated to stay secure. If you’re a plugin author, please read this post to confirm that your plugin is not affected by the same issue. Thank you to all of the plugin authors who worked closely with our security team to ensure a coordinated response.
