CVE-2019-25228Network attack vectorHinoki check available

Context URL disclosure via Referer header

Published Dec 18, 2025 · Updated Dec 18, 2025

Information disclosure in Kentico Xperience 12.0.47 and earlier allows attackers to leak virtual context URLs to third-party domains. MVC page builder and preview pages send the full virtual context URL in the HTTP Referer header when editors follow external links or load external images. Exposure requires an editor to interact with third-party content while using a virtual-context page, and reveals the context URL without reported data modification or service interruption.
