Description
CVE-2026-106137 is a race condition vulnerability in Progress Telerik UI for ASP.NET MVC versions from 2012.2.710 up to but not including 2026.3.1015. The issue involves unsafe updates to a shared class dictionary without exclusive write protection, leading to potential corruption or resource exhaustion.
