CVE-2026-12351: CWE-74 Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') in IBM MQ
IBM MQ 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 could allow a remote attacker to execute arbitrary code due to unsafe JNDI lookup processing when the IVT application is deployed.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-12351) affects IBM MQ messaging middleware in multiple versions including 9.3.x, 9.4.x, and 10.0.0. The root cause is unsafe handling of JNDI lookups in the IVT application deployment, leading to improper neutralization of special elements (CWE-74). Exploitation could result in remote code execution with no privileges or user interaction required, making it highly critical. The CVSS v3.1 base score is 9.8, reflecting high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows a remote attacker to execute arbitrary code on the affected IBM MQ server, potentially leading to full system compromise. The vulnerability affects confidentiality, integrity, and availability of the system. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. No official patch or workaround information is provided in the available data. Users should monitor IBM security advisories closely and apply updates once available. Until then, consider restricting network access to IBM MQ services and deploying additional monitoring for suspicious activity related to JNDI lookups in the IVT application.
