Summary
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.
This vulnerability is fixed in 2.18.9, 2.21.5, and 3.1.4. This vulnerability occurs in the data-binding functionality where properties intended to be ignored are incorrectly restored and become writable again.
An attacker could potentially exploit this by providing input that modifies data through these supposedly ignored properties. This could lead to unintended changes in application data, impacting data integrity.
This is a Moderate impact flaw in jackson-databind where applications enabling case-insensitive property matching alongside per-property @JsonIgnoreProperties may inadvertently expose fields to unauthorized modification.
Is CVE-2026-54515 exploited?
No exploitation is reported in the sources VulniPulse tracks: CVE-2026-54515 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.
