html injection testing

SKILL.md

Identify and exploit HTML injection vulnerabilities that allow attackers to inject malicious HTML content into web applications. This vulnerability enables attackers to modify page appearance, create phishing pages, and steal user credentials through injected forms.

HTML injection occurs when user input is reflected in web pages without proper sanitization:

| Test | Basic rendering test | | Bold | Simple formatting | | Link | Link injection | | | Image tag test | | | Style injection | | | Form hijacking |

This skill should be used when the user asks to "test for HTML injection", "inject HTML into web pages", "perform HTML injection attacks", "deface web applications", or "test content injection vulnerabilities". It provides comprehensive HTML injection attack techniques and testing methodologies. Source: sickn33/antigravity-awesome-skills.
