Older versions of WordPress make all posts vulnerable to cross-site scripting. But the cross-site scripting vulnerability in WordPress is a thing of the past now since the release of v5.1.1. The WordPress team have introduced several fixes in this new version. But first – What does a cross-site scripting vulnerability actually mean?
Dangers of cross-site scripting
Every website which has comments enabled is in danger of cross-site scripting because of the way comments are stored in the database. An attacker only needs a maliciously-crafted comment, their own website and a tricked WordPress admin. If that particular admin visits the malicious website, a cross-site request forgery (CSRF) exploit will run against the WordPress blog. That CSRF could lead to Remote Code Execution and a full take-over of the WordPress site. And you, the admin, won’t notice anything – until it’s too late.
How WordPress solved cross-site scripting vulnerabilities
WordPress 5.1.1 introduced many fixes and enhancements, but most importantly XSS-related ones. These work with the way comments are filtered. The fastest solution is to disable comments entirely – but who wants to create a non-inclusive space? The other option is to keep your WordPress sites regularly maintained. So we suggest you download the latest WordPress 5.1.1 version to safeguard your business.
Since WordPress is responsible for 30% of all websites, millions of sites are in danger. So if you’re a WordPress administrator, don’t fall victim to cross-site scripting. Also, be careful not to make these common website mistakes .
