Description
CVE-2026-124688 is a cross-site scripting (XSS) vulnerability in Progress Software's Kendo UI for jQuery versions from 2012.1.322 up to but not including 2026.4.1111. The flaw exists in the TabStrip, PanelBar, and Menu widgets when mapping a dataSource field to the spriteCssClass property. An attacker who controls this data can inject malicious markup and event-handler attributes, leading to JavaScript execution in the context of the application's origin. This can allow attackers to access data and perform actions within the victim's authenticated session.
