WordPress 5.1.1 Security and Maintenance Release
WordPress 5.1.1 is now available, since Tuesday night, March 12, 2019. This is a security and maintenance release that addresses 14 bugs. We strongly encourage you to update your sites immediately. The primary focus of this release was on security improvements and changes designed to help hosts prepare users for the minimum PHP version bump coming in 5.2.
This release also includes a pair of security fixes that handle how comments are filtered and then stored in the database. With a maliciously crafted comment, a WordPress post was vulnerable to cross-site scripting. WordPress versions 5.1 and earlier are affected by these bugs, which are fixed in version WordPress 5.1.1 Security and Maintenance Release. Updated versions of WordPress 5.0 and earlier are also available for any users who have not yet updated to 5.1.
Your WP up-to-date and never better: Experience the Safe & Secure sensation with recurrent WordPress Maintenance from owl power.
