AutoMapper is a convention-based object-object mapper in .NET. Prior to 15.1.4 and from 16.0.0 until 16.3.0, AutoMapper can recurse without an effective MaxDepth limit when mapping polymorphic graphs through Include or IncludeBase, runtime-typed object or interface members, nested Dictionary<string, object> or ExpandoObject sources, or recursive ConvertUsing type converters. Deep attacker-influenced graphs on these paths can throw an uncatchable StackOverflowException and terminate the process. This issue is fixed in versions 15.1.4 and 16.3.0.
