## Summary

Prototype Pollution in Progress Software's Kendo UI for Vue, in the @progress/kendo-vue-common package, lets a highly privileged user modify the prototype of built-in objects when they can control a field path processed by components such as the Scheduler. The attacker must be logged in with high privileges and can reach the flaw over the network, and the resulting impact is limited to partial loss of confidentiality, integrity, and availability.
