A security vulnerability in the famous WordPress SEO plugin by Yoast was just reported by the WP Scan Vulnerability Database website. Our security specialists have immediately reacted to protect all SiteGround customers and have crafted and added new security rules to our WAF (web application firewall). This means that we will actively filter any possible incoming hacking attempts that try to exploit the vulnerability.
Although Yoast SEO users are protected on our servers we still highly recommend to anyone using the plugin to update it to the latest version 1.7.4. This latest release is not vulnerable to the reported Blind SQL Injection.
