Echo: AutoMapper: security update to 13.0.1+echo.1

high Tenable Cloud Security Plugin ID 457734

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - AutoMapper is a convention-based object-object mapper in .NET. Versions prior to 15.1.1 and 16.1.1 are
 vulnerable to a Denial of Service (DoS) attack. When mapping deeply nested object graphs, the library uses
 recursive method calls without enforcing a default maximum depth limit. This allows an attacker to provide
 a specially crafted object graph that exhausts the thread's stack memory, triggering a
 `StackOverflowException` and causing the entire application process to terminate. Versions 15.1.1 and
 16.1.1 fix the issue. (CVE-2026-32933)

Solution

Update the AutoMapper library and its related packages to version 13.0.1+echo.1 or later.
