Cross-Site Scripting via ListBox Bound Text 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 releases starting with R1 2020 and prior to 2026.3.1015, the ListBox default item template renders the bound dataTextField value as raw HTML without encoding. An attacker who can modify the bound data can supply HTML containing event handlers that execute JavaScript in a user's browser when the affected list item is rendered. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.
