Summary

Progress Software Kendo UI for Angular versions from 20.0.0 before 25.1.0 contain a prototype pollution flaw in the Scheduler component, in the @progress/kendo-angular-scheduler and @progress/kendo-angular-common packages. The flaw is classified as CWE-1321 and lets a high-privileged attacker who can control a field path processed by the Scheduler modify the prototype of built-in objects. An attacker needs high privileges and the ability to control that field path, and the impact is limited to confidentiality, integrity and availability.
