CVE-2026-59889

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.18.0 until 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1, UnwrappedPropertyHandler.processUnwrapped() replays buffered JSON for a @JsonUnwrapped property and calls prop.deserializeAndSet() without a prop.visibleInView(ctxt.getActiveView()) guard, allowing a property annotated with both @JsonView and @JsonUnwrapped to be written from attacker JSON under a less-privileged active view. 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. Desde 2.18.0 hasta 2.18.9, 2.21.5, 2.22.1, 3.1.5 y 3.2.1, UnwrappedPropertyHandler.processUnwrapped() reproduce JSON almacenado en búfer para una propiedad @JsonUnwrapped y llama a prop.deserializeAndSet() sin una protección prop.visibleInView(ctxt.getActiveView()), permitiendo que una propiedad anotada con @JsonView y @JsonUnwrapped sea escrita desde JSON del atacante bajo una vista activa con menos privilegios. Este problema está corregido en las versiones 2.18.9, 2.21.5, 2.22.1, 3.1.5 y 3.2.1.
