SCA: security update for com.fasterxml.jackson.core:jackson-databind, tools.jackson.core:jackson-databind (GHSA-rmj7-2vxq-3g9f)

high Tenable Self-Hosted Container Security Plugin ID 443854

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 2.10.0 until 2.18.8, 2.21.4, and 3.1.4,
 BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() allowlists any array type based only on
 clazz.isArray(), without validating the array's component (element) type against the configured allowlist.
 A PTV built with allowIfSubTypeIsArray() plus an explicit concrete-type allowlist therefore still permits
 EvilType[] even though EvilType is not allowlisted. When Jackson deserializes the elements and no per-
 element type IDs are present, it instantiates the component type directly with no further PTV check,
 bypassing the allowlist. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4. (CVE-2026-54513)

Solution

Update the com.fasterxml.jackson.core:jackson-databind library and its related packages to version 2.18.8 or later.
