Remediation Guidance

• Anti-CSRF Tokens: Implement synchronizer token pattern. Generate unique, unpredictable tokens per session or request.
• SameSite Cookies: Set SameSite=Strict or SameSite=Lax on session cookies to prevent cross-site cookie transmission.
• Custom Headers: For AJAX requests, require custom headers (e.g., X-Requested-With) that browsers won't send cross-origin.
• Origin Validation: Verify Origin and Referer headers match your domain for state-changing requests.
• Re-authentication: For critical operations (password change, fund transfer), require password re-entry.
• Framework Protection: Use built-in CSRF protection in frameworks (Django, Rails, Spring Security, ASP.NET).
