High (8.6) in progress software telerik ui for asp.net core. EPSS 0.4% estimated probability of exploitation activity in the next 30 days.
On this page
In Progress® Telerik® UI for ASP.NET Core versions `2015.1.318` through `2026.3.1015`, the server-side FilterParser processes nested expressions in untrusted filter parameters through recursive parsing without a recursion-depth limit, while FilterLexer does not enforce an input-length limit. An unauthenticated remote attacker can exploit this if the application exposes an endpoint using DataSourceRequest model binding that is reachable without authentication. Deeply nested filters can trigger parsing errors during model binding or cause `StackOverflowException`. This issue is fixed in version `2026.4.1111`.
