Echo: com.fasterxml.jackson.core:jackson-databind: security update to 2.20.2+echo.1tools.jackson.core:jackson-databind: security update to 3.1.4

medium Tenable Self-Hosted Container Security Plugin ID 460344

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 2.8.0 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. (CVE-2026-54515)

Solution

Update the com.fasterxml.jackson.core:jackson-databind library and its related packages to version 2.20.2+echo.1 or later.
