XSS refers to the practice of injecting malicious code into a user’s browser, which might be exploited to steal sensitive information, change the displayed web pages, or even redirect the user to another website. Since WordPress is often used to host websites with user-generated content, it is considered a high risk platform for XSS vulnerabilities. Fortunately, WordPress comes with many built-in protection mechanisms that can help prevent XSS attacks. These built-in security features include the sanitization of input data, the use of input filtering and validation, and the application of content filters. However, there are also security issues that arise when these built-ins are used on their own. This is especially true when you have a high volume of user-generated content. Consequently, it is essential to regularly review your code, looking for XSS issues.
What is XSS?
XSS is a type of injection attack that occurs when an attacker injects malicious code into a user’s browser. When the code is executed, it can steal sensitive information, change the displayed web pages, or even redirect the user to another website.

What is an XSS?
XSS is the practice of injecting malicious code into a user’s browser, which might be exploited to steal sensitive information, change the displayed web pages, or even redirect the user to another website.
The most common way XSS exploits occur is when a user clicks on an email link that contains malicious code in the link’s URL. This code can then be executed by the client, and if it gets past WordPress's built-in protection mechanisms, it could allow hackers to do pretty much anything they want with your site.
What is an XSS vulnerability?
An XSS vulnerability is a security flaw in the website's software that allows hackers to inject their own content into a website. When this happens, the hacker can access sensitive information, change the displayed web pages, or even redirect the user to another website. This type of vulnerability is especially dangerous when it comes to user-generated content like posts and comments.
