CVE-2026-11724 · Severity: high · CVSS 8.5 · Published 2026-11-04

IBM MQ is an enterprise message queuing system used to route data between applications and systems. Its Managed File Transfer component allows authenticated users to transfer files using scripts. An authenticated attacker can exploit improper validation of script metadata to execute arbitrary code on the file transfer agent host, potentially compromising the entire messaging infrastructure.

## How to fix

- Fixed in IBM MQ 9.2.0.46, 9.3.0.43, 9.4.0.30 LTS, 10.0.0.6 LTS, 10.0.1.0 CD

## Technical details

The vulnerability exists in IBM MQ's Managed File Transfer component due to improper input validation (CWE-20) of metadata used during script execution. An authenticated attacker with network access can craft malicious script metadata that bypasses validation controls, allowing arbitrary code execution on the MFT agent host. The attack requires authentication and higher complexity, but impacts multiple versions across LTS and CD release streams.

## Affected products

- 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, 10.0.0.0 through 10.0.0.5 LTS and CD
