2.22.0→2.22.1jackson-databind has case-insensitive deserialization bypasses per-property @JsonIgnoreProperties
CVE-2026-54515 / GHSA-5jmj-h7xm-6q6v
More information
Details
Summary
In
BeanDeserializerBase.createContextual(), per-property@JsonIgnorePropertiesexclusions are applied by_handleByNameInclusion(), producing acontextualdeserializer whoseBeanPropertyMaphas the ignored properties removed. The subsequent per-property case-insensitivity block (triggered by@JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) rebuilds fromthis._beanProperties(the original, unfiltered map) instead ofcontextual._beanProperties, then overwrites the filtered map — restoring every property_handleByNameInclusionhad just removed. The ignored property becomes writable again.Impact
An application that both enables case-insensitive matching and relies on per-property
@JsonIgnorePropertiesto keep a field unwritable can have that field set from untrusted JSON (mass-assignment-style write).Affected / Patched
Will be fixed in 2.18.9, 2.21.5, 2.22.1 and 3.1.4.
