Echo: com.fasterxml.jackson.core:jackson-databind: security update to 2.21.4tools.jackson.core:jackson-databind: security update to 3.1.4

medium Tenable Cloud Security Plugin ID 462123

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data
 Processor. From 2.21.0 until 2.21.4 and 3.1.4, POJOPropertiesCollector._renameProperties() allows a
 property with @JsonProperty("renamed") on the getter and @JsonIgnore on the setter to be renamed rather
 than dropped. With MapperFeature.INFER_PROPERTY_MUTATORS enabled (default), the private backing field is
 retained; during deserialization BeanDeserializerFactory.addBeanProps() sees hasField()==true, builds a
 FieldProperty, and makes the backing field writable. An attacker supplying the renamed JSON key writes the
 backing field directly, bypassing the @JsonIgnore on the setter. This vulnerability is fixed in 3.1.4.
 (CVE-2026-54516)

Solution

Update the com.fasterxml.jackson.core:jackson-databind library and its related packages to version 2.21.4 or later.
