CVE-2026-10751: CWE-502 Deserialization of Untrusted Data in IBM MQ
IBM MQ Java and JMS client libraries could allow an authenticated attacker to execute arbitrary code on client applications due to a deserialization filter bypass in exception handling.
AI Analysis
Technical Summary
IBM MQ Java and JMS client libraries contain a deserialization vulnerability (CWE-502) where an attacker can bypass deserialization filters during exception handling. This flaw allows an authenticated attacker with low privileges to execute arbitrary code on client applications. The vulnerability affects specific versions of IBM MQ client libraries, namely 9.1.0.0 through 10.0.0.0. The CVSS 3.1 base score is 7.5, reflecting high impact on confidentiality, integrity, and availability. No vendor patch or mitigation details are currently available in the provided data.
Potential Impact
Successful exploitation enables an authenticated attacker to execute arbitrary code on client applications using IBM MQ Java and JMS client libraries. This compromises confidentiality, integrity, and availability of the affected client systems. The attack requires authentication and has a high attack complexity.
Mitigation Recommendations
Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until an official fix is available, restrict access to IBM MQ client applications to trusted users only and monitor for suspicious activity related to deserialization. Avoid using untrusted data in client applications where possible.
