      "value": "jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.8.0 until 2.18.9, 2.21.5, and 3.1.4, in BeanDeserializerBase.createContextual(), per-property @JsonIgnoreProperties exclusions are applied by _handleByNameInclusion(), producing a contextual deserializer whose BeanPropertyMap has the ignored properties removed. The subsequent per-property case-insensitivity block (triggered by @JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) rebuilds from this._beanProperties (the original, unfiltered map) instead of contextual._beanProperties, then overwrites the filtered map — restoring every property _handleByNameInclusion had just removed. The ignored property becomes writable again. This vulnerability is fixed in 2.18.9, 2.21.5, and 3.1.4."

      "value": "jackson-databind contiene la funcionalidad de enlace de datos de propósito general y el modelo de árbol para el procesador de datos Jackson. Desde 2.8.0 hasta 2.18.9, 2.21.5 y 3.1.4, en BeanDeserializerBase.createContextual(), las exclusiones @JsonIgnoreProperties por propiedad son aplicadas por _handleByNameInclusion(), produciendo un deserializador contextual cuyo BeanPropertyMap tiene las propiedades ignoradas eliminadas. El bloque de insensibilidad a mayúsculas y minúsculas por propiedad subsiguiente (activado por @JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) reconstruye desde this._beanProperties (el mapa original, sin filtrar) en lugar de contextual._beanProperties, luego sobrescribe el mapa filtrado - restaurando cada propiedad que _handleByNameInclusion acababa de eliminar. La propiedad ignorada vuelve a ser escribible. Esta vulnerabilidad está corregida en 2.18.9, 2.21.5 y 3.1.4."
