SCA: security update for com.fasterxml.jackson.core:jackson-databind, tools.jackson.core:jackson-databind (GHSA-hgj6-7826-r7m5)

medium Tenable Cloud Security Plugin ID 443846

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 2.0.0 until 2.18.8, 2.21.4, and 3.1.4, JDKFromStringDeserializer constructed
InetSocketAddress with new InetSocketAddress(host, port), which performs eager DNS name resolution for
hostname inputs at deserialization time. An application that binds untrusted JSON into a type containing
an InetSocketAddress field issues an attacker-chosen DNS query during readValue, before any application-
level validation or connect logic. The fix uses InetSocketAddress.createUnresolved(host, port), deferring
DNS to an explicit connect. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4. (CVE-2026-54514)

Solution

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