Open IBM MQ listeners are free shots. CVE-2026-10747 is a pre-auth heap overflow (CVSS 10) in protocol handling. Packets before login can DoS or RCE the queue manager. Censys still finds internet consoles. Ship fixed LTS builds and close public listeners. https://www.ibm.com/support/pages/security-bulletin-ibm-mq-vulnerable-unauthenticated-remote-code-execution-cve-2026-10747
Post summary
The text discloses CVE-2026-10747 as a critical pre-auth heap overflow in IBM MQ (CVSS 10) enabling DoS/RCE, notes internet-exposed instances via Censys, and primarily urges deployment of fixed LTS builds and closure of public listeners as remediation.
