Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement context-aware output encoding for all user-supplied data before rendering in HTML, validate and sanitize all inputs on the server side, and consider implementing a Content Security Policy (CSP) to mitigate XSS execution.
