It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-11711 in the wild and no public exploit code.\n\nAffected product: IBM WebSphere Application Server. 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-2026-11711/ (Markdown: https://insights.sbomify.com/CVE-2026-11711/index.md)","id":"CVE-2026-11711","markdown":"https://insights.sbomify.com/CVE-2026-11711/index.md","name":"CVE-2026-11711","record":{"aliases":["GHSA-qxf8-2p95-9hvv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"WebSphere Application Server","requires_auth":"none","summary":"Attackers can execute arbitrary code via deserialization flaws in the Name Service component of IBM WebSphere Application Server.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"IBM WebSphere Application Server 9.0 and 8.5 is affected by a deserialization vulnerability in the Name Service component.","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 WebSphere Application Server prior to 9.0.5.29 and 8.5.5.31 are affected by multiple vulnerabilities","id":"CVE-2026-11711","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"IBM WebSphere Application Server is affected by a cross-site scripting vulnerability","id":"CVE-2026-11712"},"packages":[],"prev":{"headline":"IBM WebSphere Application Server is affected by an HTTP request smuggling vulnerability","id":"CVE-2026-11710"},"products":["WebSphere Application Server"],"published":"2026-09-18","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":"partial"},"state":"PUBLISHED","updated":"2026-09-19","vendors":["IBM"]},"summary":"Attackers can execute arbitrary code via deserialization flaws in the Name Service component of IBM WebSphere Application Server.","url":"https://insights.sbomify.com/CVE-2026-11711/"}
