AI-suggested

This vulnerability is fixed in jackson-databind versions 2.18.8, 2.21.4, and 3.1.4. Users should upgrade to one of these versions or later to remediate the issue. No additional vendor advisories indicate alternative mitigations or that no action is required.

Description

A vulnerability in jackson-databind affects versions from 2.0.0 up to but excluding 2.18.8, 2.21.4, and 3.1.4. The issue arises because the JDKFromStringDeserializer class eagerly resolves DNS names during deserialization of InetSocketAddress fields, potentially causing an attacker-controlled DNS query before application validation. The vulnerability is fixed by deferring DNS resolution until an explicit connect call. This flaw has a CVSS score of 7.5 and is rated as medium severity.
