✨ To find XSS (Cross-Site Scripting) bugs, you can use a combination of manual testing and automated tools.

Some steps you can follow to find XSS:

➡️ identify potential entry points for XSS attacks, such as input fields in web forms, query parameters in URLs, or file uploads.

➡️ Use a web application scanner to test these entry points for XSS vulnerabilities.

These scanners can automatically scan your web application and identify potential vulnerabilities, including XSS.

➡️ Manually review your website’s code for any places where user-supplied input is not properly sanitized or validated.

For example, look for places where the website includes user input in the page without properly encoding it first.

➡️ Test the website by trying to inject various types of malicious input, such as JavaScript code, into different parts of the website.

For example, try entering JavaScript code into forms, URL parameters, and other inputs to see if the website is vulnerable to XSS attacks.

➡️ If you find any potential XSS vulnerabilities, verify them by attempting to exploit them.

This will help you confirm that the issue is real and that it needs to be fixed

⭐ Once you have identified and verified any XSS vulnerabilities, work with your development team to fix the issues and prevent them from happening again in the future.
