Questions about CVE-2026-13289
Is CVE-2026-13289 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 of IBM MQ does not safely handle external entity references when it processes XML data. The vendor says this could expose sensitive information or consume memory resources.Source: ibm.com
Which versions are affected by CVE-2026-13289?
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?
Affected versions are IBM MQ 9.2.0.0 to 9.2.0.44 LTS, 9.3.0.0 to 9.3.0.42 LTS, 9.4.0.0 to 9.4.0.26 LTS, 9.4.0.0 to 9.4.5.1 CD, and 10.0.0.0 to 10.0.0.5 LTS and CD.
