CVE-2025-36005Network attack vector

Cross-session TLS data disclosure via certificate misvalidation

Published Jul 24, 2025 · Updated Aug 17, 2025

Information disclosure in IBM MQ Operator Internet Pass-Thru allows remote attackers to read data from another TLS session. Internet Pass-Thru improperly validates certificates when proxying TLS connections to the same hostname and port, exposing one session's data to another. Exploitation requires the Internet Pass-Thru proxy and another TLS session for that destination; the reported consequence is disclosure only.
