CVE-2026-77310

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. Prior to versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1 on their respective release lines, the java.net.InetAddress branch of FromStringDeserializer.Std._deserialize() calls InetAddress.getByName() on attacker-controlled input, causing eager DNS resolution during deserialization and enabling DNS-based server-side request forgery and internal-host enumeration. This issue is fixed in versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1.

Summary		(es) jackson-databind contiene la funcionalidad de enlace de datos de propósito general y el modelo de árbol para el procesador de datos Jackson. Antes de las versiones 2.18.9, 2.21.5, 2.22.1, 3.1.5 y 3.2.1 en sus respectivas líneas de lanzamiento, la rama java.net.InetAddress de FromStringDeserializer.Std._deserialize() llama a InetAddress.getByName() en una entrada controlada por el atacante, causando una resolución DNS anticipada durante la deserialización y permitiendo la falsificación de petición del lado del servidor basada en DNS y la enumeración de hosts internos. Este problema está solucionado en las versiones 2.18.9, 2.21.5, 2.22.1, 3.1.5 y 3.2.1.
