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 dataUpdate to the latest patched version of the Automotive Car Dealership Business theme once available. Until a patch is released, implement output encoding and input validation on all user-supplied data, and consider deploying a Web Application Firewall (WAF) as a compensating control.
