WordPress 4.0.1 is now available. This is a critical security release<\/strong> for all previous versions and we strongly encourage you to update your sites immediately.<\/p>\n Sites that support automatic background updates will be updated to WordPress 4.0.1 within the next few hours. If you are still on WordPress 3.9.2, 3.8.4, or 3.7.4, you will be updated to 3.9.3, 3.8.5, or 3.7.5 to keep everything secure. (We don\u2019t support older versions, so please update to 4.0.1 for the latest and greatest.)<\/p>\n WordPress versions 3.9.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. This was reported by Jouko Pynnonen<\/a>. This issue does not affect version 4.0, but version 4.0.1 does address these eight security issues:<\/p>\n Version 4.0.1 also fixes 23 bugs with 4.0, and we’ve\u00a0made two hardening changes, including better validation of EXIF data we are extracting from uploaded photos. Reported by Chris Andr\u00e8 Dale<\/a>.<\/p>\n We appreciated the\u00a0responsible disclosure<\/a> of these issues directly to our security team.\u00a0For more information, see the release notes<\/a> or consult the list of changes<\/a>.<\/p>\n Download WordPress 4.0.1<\/a> or venture over to Dashboard \u2192 Updates<\/strong> and simply click \u201cUpdate Now\u201d.<\/p>\n Already testing WordPress 4.1? The second beta is now available (zip<\/a>) and it contains these security fixes. For more on 4.1, see the beta 1 announcement post<\/a>.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" WordPress 4.0.1 is now available.
