An authenticated attacker can exploit this flaw by sending specifically crafted serialized data to the application. Successful exploitation of this vulnerability can result in a denial of service (DoS) or potentially lead to remote code execution (RCE) with the privileges of the MQ Operator service. This vulnerability is particularly critical in containerized environments where the operator manages message queuing infrastructure. Organizations utilizing IBM MQ Operator should verify their current versions and monitor for updates from IBM to address this deserialization flaw.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-12148 allows an authenticated attacker to compromise the availability and integrity of the IBM MQ infrastructure.
