FKIE_CVE-2026-32933

Vulnerability from fkie_nvd - Published: 2026-03-20 03:16 - Updated: 2026-04-08 20:52
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.

Las versiones anteriores a la 15.1.1 y 16.1.1 son vulnerables a un ataque de denegaci\u00f3n de servicio (DoS). Al mapear grafos de objetos profundamente anidados, la biblioteca utiliza llamadas a m\u00e9todos recursivas sin imponer un l\u00edmite de profundidad m\u00e1xima predeterminado. Esto permite a un atacante proporcionar un grafo de objetos especialmente dise\u00f1ado que agota la memoria de pila del hilo, lo que desencadena una \u0027StackOverflowException\u0027 y provoca la terminaci\u00f3n de todo el proceso de la aplicaci\u00f3n.
