Summary

Progress Kendo UI for jQuery versions from 2014.3.1119 before 2026.3.1015 are affected. The Scheduler Day, Timeline, Month, and Agenda views insert resource color values into quoted event wrapper attributes without proper encoding, which is a cross-site scripting flaw (CWE-80). An attacker who can control a resource color can inject extra HTML attributes, including event handlers, and run JavaScript in a user's browser when the affected event is interacted with. Exploitation requires user interaction and can affect the confidentiality and integrity of data the application can access.
