CVE-2026-124697

Description

In Progress Kendo UI for jQuery, Chart shared-tooltip rendering treats bound category and series-name values as raw HTML. An attacker who can influence values consumed by an affected Chart can inject markup that executes as JavaScript when a user displays the shared tooltip. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. Version 2016.2.607 or earlier may be affected, but earlier releases have not been verified. The latest vulnerable version is 2026.3.1015; the issue is fixed in version 2026.4.1111.
