Can this skill help bypass Web Application Firewalls (WAFs)?

It provides several advanced techniques such as character encoding, tag splitting, and null byte injection to help testers evaluate the effectiveness of their WAF filters.

Which programming languages are covered for remediation?

The skill provides specific code examples and best practices for preventing injection in PHP, Python (specifically Jinja2/Flask), and JavaScript environments.

What is the primary difference between HTML injection and XSS?

HTML injection focus on rendering unauthorized HTML tags to modify page appearance or create fake forms, whereas XSS (Cross-Site Scripting) involves executing malicious JavaScript code in the victim's browser.

Does this skill support automated security testing?

Yes, it includes workflows for using industry-standard tools like Burp Suite and OWASP ZAP, as well as custom Python scripts for automated fuzzing of injection points.
