WordPress Releases Version 4.1.2, Calls It A “Critical Security Release”
WordPress webmasters advised to upgrade immediately to prevent anonymous users from compromising websites.
WordPress has pushed out version 4.1.2 of its content management software, calling it a “critical security release” and advising all users to upgrade immediately.
“WordPress versions 4.1.1 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site,” said Gary Pendergast, a member of the WordPress security team, in a company blog post today.
This update also fixes three additional security issues, WordPress says:
- In WordPress 4.1 and higher, files with invalid or unsafe names could be uploaded.
- In WordPress 3.9 and higher, a very limited cross-site scripting vulnerability could be used as part of a social engineering attack.
- Some plugins were vulnerable to an SQL injection vulnerability.
WordPress users can update their websites via the website dashboard or by downloading WordPress 4.1.2. Many web hosts offer automatic WordPress updates and those are already underway.
