This vulnerability allows a remote attacker to force the application to perform an attacker-chosen DNS (Domain Name System) query. This occurs when untrusted JSON input containing specific network address information is processed, potentially leading to the disclosure of sensitive network configuration details. ## Vendor advisories - **RHSA-2026:36002** · Red Hat · fixed in: Red Hat build of Quarkus 3.27.4.SP2 · released 2026-07-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:36002) - **RHSA-2026:36013** · Red Hat · fixed in: Red Hat build of Quarkus 3.33.2.SP2 · released 2026-07-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:36013) - **Red Hat VEX** · Moderate · affected: Cryostat 4, OpenShift Developer Tools and Services, OpenShift Serverless, Red Hat AI Inference Server, Red Hat AMQ Broker 7, Red Hat AMQ Clients, … · no fix planned: Cryostat 4, OpenShift Developer Tools and Services, OpenShift Serverless, Red Hat AI Inference Server, … · updated 2026-10-20 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-54514.json) **jackson-databind: jackson-databind: Information Disclosure via Eager DNS Resolution** — rated Moderate by Red Hat.
