After nearly 7 million downloads of WordPress 3.6, we are pleased to announce the availability of version 3.6.1. This maintenance release fixes 13 bugs in version 3.6, which was a very smooth release.
WordPress 3.6.1 is also a security release for all previous WordPress versions and we strongly encourage you to update your sites immediately. It addresses three issues fixed by the WordPress security team:
- Remote Code Execution: Block unsafe PHP unserialization that could occur in limited situations and setups. Reported by Tom Van Goethem.
- Privilege Escalation: Prevent a user with an Author role, using a specially crafted request, from being able to create a post “written by” another user. Reported by Anakorn Kyavatanakij.
- Open Redirect: Fix insufficient input validation that could result in redirecting or leading a user to another website. Reported by Dave Cummo, a Northrup Grumman subcontractor for the U.S. Centers for Disease Control and Prevention.
Additionally, we’ve adjusted security restrictions around file uploads to mitigate the potential for cross-site scripting.
Download WordPress 3.6.1 or update now from the Dashboard → Updates menu in your site’s admin area.
