AI-suggested

Upgrade to version 2026.3.1015 or later, where the issue is fixed. Until then, ensure that aggregation endpoints are not exposed without authentication to prevent exploitation.

Description

A memory exhaustion vulnerability exists in In Progress® Telerik® UI for ASP.NET Core versions 2015.1.318 through 2026.3.811. Repeated server-side aggregation requests cause dynamic assemblies and load contexts to accumulate, leading to increased process memory consumption. An unauthenticated remote attacker can exploit this if the aggregation endpoint is exposed without authentication, potentially causing denial of service due to resource exhaustion. The issue is fixed in version 2026.3.1015.
