CVE-2026-18672 is an insufficient validation vulnerability in the RadImageEditor component of Progress Telerik UI for AJAX versions prior to 2026.3.812. Client-supplied state influencing the control's image-cache processing is not adequately constrained, allowing an attacker to influence the file returned by the image cache. This constitutes a path traversal condition that can cause the control to access files outside the intended image directories.
