User Controllable HTML Element Attribute (Potential XSS)

Remediation\n\n1. Input validation: Implement strict validation for all user input that might be reflected in HTML attributes.\n2. Output encoding: Properly encode all user data before inserting it into HTML attributes using context-appropriate encoding.\n3. Content Security Policy: Implement CSP headers to mitigate potential XSS attacks.\n4. Use safe APIs: Utilize framework-provided safe APIs for generating HTML content that automatically handle encoding.\n\n### About\n\nUser Controllable HTML Element Attribute vulnerabilities occur when user input can directly influence HTML attribute values without proper validation or encoding. This creates potential injection points for cross-site scripting (XSS) attacks where malicious scripts could be injected into HTML attributes.\n\n### Risks\n\nHigh This vulnerability can lead to cross-site scripting attacks, session hijacking, credential theft, malware injection, and complete compromise of user sessions and sensitive data.
