Until a patch is available, organizations should monitor IBM's official advisories for updates and consider mitigating controls specific to JNDI lookup usage in the IVT application context.
Description
CVE-2026-12351 is a critical vulnerability in IBM MQ affecting versions 9.3.0.0 through 9.3.0.41 LTS, 9.3.0.0 through 9.3.5.1 CD, 9.4.0.0 through 9.4.0.25 LTS, 9.4.0.0 through 9.4.5.1 LTS, and 10.0.0.0. It involves improper neutralization of special elements in output used by a downstream component, specifically unsafe JNDI lookup processing when the IVT application is deployed. This flaw could allow a remote attacker to execute arbitrary code on affected systems.
