Cross-Site Scripting via TabStrip, Menu, and PanelBar Image URLs in Kendo UI for jQuery

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

In Progress® Kendo® UI for jQuery prior to 2026.3.1015, the TabStrip, Menu, and PanelBar components insert data source imageUrl values into single-quoted image src attributes without proper escaping. An attacker who can modify an image URL can inject additional HTML attributes, including event handlers, and execute JavaScript in a user's browser when the affected component renders the image. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015.
