AI-suggested
Upgrade AutoMapper to version 15.1.4 or later if using a version prior to 16.0.0, or to version 16.3.0 or later if using versions from 16.0.0 to 16.3.0. These versions contain the official fix for the uncontrolled recursion vulnerability.
Description
AutoMapper versions prior to 15.1.4 and from 16.0.0 up to but not including 16.3.0 contain an uncontrolled recursion vulnerability. This occurs when mapping polymorphic graphs or certain complex object types, potentially causing an uncatchable StackOverflowException that terminates the process. The issue is fixed in versions 15.1.4 and 16.3.0.
