Summary
IBM MQ Managed File Transfer has an XML external entity injection flaw that lets a remote attacker, logged in with low privileges and without any user action, expose sensitive information or consume memory resources by getting the product to process crafted XML data.
Read the original description
IBM MQ 9.2.0.0 through 9.2.0.44 LTS, 9.3.0.0 through 9.3.0.42 LTS, 9.4.0.0 through 9.4.0.26 LTS, 9.4.0.0 through 9.4.5.1 CD, and 10.0.0.0 through 10.0.0.5 LTS and CD is vulnerable to an XML external entity injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.

Questions about CVE-2026-13284
Is CVE-2026-13284 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The Managed File Transfer component processes XML data and allows XML external entity injection. A remote attacker could use this to expose sensitive information or consume memory resources when XML data is processed.Source: ibm.com
Which versions are affected by CVE-2026-13284?
MQ: from 9.2.0.0 through 9.2.0.44; from 9.3.0.0 through 9.3.0.42; from 9.4.0.0 through 9.4.0.26; from 9.4.0.0 through 9.4.5.1; from 10.0.0.0 through 10.0.0.5.Source: cve.now feed data
Am I affected, and how do I check?
