CVE-2026-13265
MediumCVSS 6.8Summary
IBM MQ 9.1.0.0 through 9.1.0.37 LTS, 9.2.0.0 through 9.2.0.43 LTS, 9.3.0.0 through 9.3.0.41 LTS, 9.3.0.0 through 9.3.5.1 CD, 9.4.0.0 through 9.4.0.25 LTS, 9.4.0.0 through 9.4.5.1 CD, and 10.0.0.0 could allow an authenticated attacker with MFT publish authority to obtain sensitive information or cause a denial of service due to XML external entity injection in the mqweb MFT REST API.
Risk Assessment
An authenticated attacker with MFT publish authority can obtain sensitive information or cause a denial of service, potentially leading to data leakage and system disruption. This poses a threat to confidentiality and availability.
Recommendation
Update IBM MQ to a version that includes the fix for this issue. Until then, restrict MFT publish authority and monitor for unusual requests to the mqweb MFT REST API.
