CVE-2026-13293: CWE-502 Deserialization of Untrusted Data in IBM MQ
IBM MQ 9.1.0.0 through 9.1.0.37 LTS, 9.2.0.0 through 9.2.0.43 LTS, 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 CD, and 10.0.0.0 could allow a remote authenticated attacker to execute arbitrary code on the system due to the deserialization of untrusted data.
AI Analysis
Technical Summary
IBM MQ versions 9.1.0.0 through 9.1.0.37 LTS, 9.2.0.0 through 9.2.0.43 LTS, 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 CD, and 10.0.0.0 contain a deserialization of untrusted data vulnerability (CWE-502). This flaw allows a remote authenticated attacker to execute arbitrary code by exploiting the unsafe deserialization process within the product. The CVSS v3.1 base score is 8.8, indicating a high severity with network attack vector, low attack complexity, and no user interaction required.
Potential Impact
Successful exploitation of this vulnerability could lead to complete compromise of confidentiality, integrity, and availability of the affected IBM MQ system. An attacker with valid authentication credentials could execute arbitrary code remotely, potentially leading to full system control.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the current data. Until a patch is available, restrict access to IBM MQ services to trusted users only and monitor for suspicious activity involving deserialization processes.
