Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-11729 in the wild and no public exploit code.\n\nAffected product: IBM MQ. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-11729/ (Markdown: https://insights.sbomify.com/CVE-2026-11729/index.md)","id":"CVE-2026-11729","markdown":"https://insights.sbomify.com/CVE-2026-11729/index.md","name":"CVE-2026-11729","record":{"aliases":["GHSA-fgh4-pvm7-m8pf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM MQ messaging","requires_auth":"low_privilege","summary":"An authenticated attacker can execute arbitrary code in client applications via unsafe deserialization leading to JNDI injection in IBM MQ.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"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 to execute arbitrary code in client applications due to unsafe deserialization that enables JNDI injection attacks.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"IBM MQ Java messaging is vulnerable to remote code execution","id":"CVE-2026-11729","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Insufficient session randomness vulnerability exists in certain NETGEAR EX Series Models","id":"CVE-2026-11730"},"packages":[],"prev":{"headline":"IBM MQ .NET client is vulnerable to remote code execution","id":"CVE-2026-11728"},"products":["MQ"],"published":"2026-09-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-16","vendors":["IBM"]},"summary":"An authenticated attacker can execute arbitrary code in client applications via unsafe deserialization leading to JNDI injection in IBM MQ.","url":"https://insights.sbomify.com/CVE-2026-11729/"}
