## Overview

Prototype Pollution in the Scheduler component (@progress/kendo-angular-scheduler and @progress/kendo-angular-common) in Progress Software Kendo UI for Angular versions prior to 25.1.0 allows a high-privileged attacker who can control a field path processed by the Scheduler to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.

## Affected

- `@progress/kendo-angular-scheduler < 25.1.0`
