  "title": "Constructor-mapping recursion bypass in AutoMapper",
  "summary": "Affected AutoMapper releases can fail to enforce mapping depth limits when recursively nested destination objects are created through constructor parameters. An attacker able to supply deeply nested data for such a mapping may terminate the application process through stack exhaustion, even when a depth limit is configured.",
  "mitigation": "Upgrade AutoMapper to 16.3.0 or 15.1.4. Until then, reject or limit nested input before mapping; for compatible destination types, disable constructor mapping and use property mapping instead.",
