Update Your WordPress Version!
There was a vulnerability found in the WordPress core files.
The security hole is specifically about posts that are set to “Private” status. Anyone subscribed to your website could gain access to the private information. The fix for this was just released today in WordPress version 4.5.3. Even if you don’t have any pages or posts set to “Private,” you should always update WordPress immediately as new versions become available.
