研究方向
Investigate the UI components that render user input (e.g., chat messages, usernames) and check for missing output sanitization. Look for direct innerHTML usage or unsafe React dangerouslySetInnerHTML. Identify which inputs are vulnerable using the screenshot as reference. After locating the vulnerable code, apply a sanitization library like DOMPurify or ensure proper HTML escaping. Test with common XSS payloads to confirm the fix works.
