WordPress 5.8.3 Security Release
https://www.wordfence.comOn January 6, 2022, the WordPress core team released WordPress version 5.8.3, which contains security patches for 4 high-severity vulnerabilities. These patches were backported to every version of WordPress since 3.7.
Most WordPress sites are not in danger from these vulnerabilities, thanks to the WordPress core team deploying patches to all sites that allow automatic core updates for security patches, which is the default behavior.
Sites on read-only filesystems as well as sites that have explicitly disabled automatic core updates via setting define( 'WP_AUTO_UPDATE_CORE', false ); in wp-config.php may not yet have updated, and we urge owners of these sites to do so as soon as possible.
