Cross-site scripting (XSS) is a security risk in which hackers inject malicious code into any vulnerable website’s software. The code is activated in the victim’s browser, allowing the attacker to impersonate the victim, perform any actions that the victim is capable of performing, and access any of the victim’s data. If the victim user has privileged access to the application, the attacker may be able to gain complete control of the application’s functionality and data. This article will show you how to use the Prevent XSS Vulnerability plugin to prevent XSS vulnerabilities in WordPress.
