  "summary": "AutoMapper installations prior to the fixed releases may fail to enforce mapping-depth limits for certain polymorphic, runtime-typed, dictionary, dynamic, or converter-driven mappings. An attacker who can supply deeply nested data that reaches one of these paths can cause the application process to terminate.",
  "mitigation": "Upgrade AutoMapper to 16.3.0 or 15.1.4. Until upgraded, limit nesting depth before mapping untrusted input; also set MaxDepth on affected derived and runtime-typed maps where applicable.",
