CVE-2026-124689
Cross-Site Scripting in Kendo UI for jQuery ActionSheet Header Labels
In Progress Kendo UI for jQuery versions 2026.3.1014 up to, but not including, 2026.4.1110, ActionSheet does not encode title, subtitle, and header button label values before rendering them. An attacker who can influence these values can inject markup that executes as JavaScript when a user opens the ActionSheet. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The report identifies version 2026.3.1014; the first affected release has not been established.
