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 Product Filter Widget for Elementor to a version newer than 1.0.6, or apply any available security patch from the vendor. If immediate update is not possible, consider restricting access to the plugin endpoints or deploying a WAF rule to block XSS attack patterns.
