CVE-2026-13285Network attack vector

Information disclosure and memory exhaustion via XML entities

Published Sep 14, 2026 · Updated Sep 14, 2026

XXE in IBM MQ 9.1.0.0 through 9.4.5.1 and 10.0.0.0 allows remote attackers to disclose data or exhaust memory via XML. The Managed File Transfer agent parses transfer-request XML delivered through its command queue without preventing external entity resolution. Reachability requires the ability to submit XML transfer messages to an affected agent; impact is limited to sensitive-information exposure and memory exhaustion.
