Vulnerability Title
jackson-databind: @JsonIgnore on a Record property is bypassed with a PropertyNamingStrategy
Source: CVE Program / CVE List V5
Vulnerability Description
jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.15.0 until 2.18.8, 2.21.4, and 3.1.4, Java Records using a PropertyNamingStrategy can bypass @JsonIgnore because POJOPropertiesCollector._removeUnwantedIgnorals() records an ignored component under its original implicit name before _renameUsing() applies the naming strategy, allowing the renamed JSON key to be assigned to the Record constructor parameter. This issue is fixed in versions 2.18.8, 2.21.4, and 3.1.4.
