Name of the Vulnerable Software and Affected Versions
Telerik UI for AJAX versions prior to 2026.2.708
Description
The internal LayoutBuilder control processes client-state XML without disabling Document Type Definition (DTD) processing. This allows an unauthenticated attacker to cause a denial of service through recursive XML entity expansion, a technique where nested entities are used to exhaust system resources.
Recommendations
Update to version 2026.2.708 or later.
Fix
XML Entity Expansion
