Origin Trial Features Context - Data Module
"""

DESCRIPTION = """
Origin Trials allow testing experimental browser features.
These features may have security vulnerabilities or bypasses that can be
exploited for XSS, especially when user input interacts with experimental APIs.

Vulnerability occurs when:
- Experimental APIs process user input unsafely
- Origin trial features have security weaknesses
- Feature flags are user-controlled
- Experimental APIs bypass security mechanisms
- Trial tokens are manipulated

Common injection points:
- Experimental API parameters
- Feature flag values
- Origin trial token manipulation
- Experimental DOM APIs
- New event handlers
"""

ATTACK_VECTOR = """
1. Experimental API injection:
   experimentalAPI.method(USER_INPUT)

2. Feature flag injection:
   if (experimentalFeature(USER_INPUT)) {
       // vulnerable code
   }

3. Token manipulation:
   <meta http-equiv="origin-trial" content="USER_INPUT">

4. Experimental DOM API:
   element.experimentalProperty = USER_INPUT;

5. New event handler:
   element.addEventListener('experimentalEvent', () => {
       USER_INPUT
   });
"""

REMEDIATION = """
1. Avoid using experimental features in production
2. Sanitize all user input for experimental APIs
3. Validate origin trial tokens
4. Monitor experimental feature security updates
5. Use Content Security Policy
6. Audit all experimental API usage
7. Test experimental features thoroughly
8. Keep browsers updated
