WordPress 4.8.3 has just been released so if you haven’t upgraded your WordPress website yet, then you should do so as soon as possible.
Version 4.8.3 is an important security update that will fix a serious programming flaw that can potentially expose WordPress-powered websites to the possibility of being attacked and hijacked by hackers by means of injecting malicious SQL database commands.
This version will fix all below bugs:
- The bug CVE-2017-14723, was discovered and reported by security researcher Anthony Ferrara in September. The WordPress core is not affected, the vulnerability lies in WPDB, a set of functions used to talk to the WordPress database, and its ability to include sprint tokens.
- The buggy code: $wpdb->prepare(), can create unexpected and unsafe queries and potentially allow malicious SQL injection in version 4.8.2 and earlier. This newly-released WordPress 4.8.3 security update addresses this flaw by changing the behavior of the esc_sql() function and hardening it to protect it from attacks via plugins and themes
