> Description : 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.
> *NVD URL :* [https://nvd.nist.gov/vuln/detail/CVE-2026-54515]
> Fix Version : 2.18.9, 2.21.5, and 3.1.4.
