Canvas JavaScript Security Extended Tests (SECU-04.2).
Extended comprehensive tests for canvas JavaScript security:
- Malicious JavaScript pattern detection
- eval() and Function() constructor variants
- DOM manipulation and data exfiltration
- Canvas component validation
- Static analysis validation
