An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-105442 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-2026-105442/ (Markdown: https://insights.sbomify.com/CVE-2026-105442/index.md)","id":"CVE-2026-105442","markdown":"https://insights.sbomify.com/CVE-2026-105442/index.md","name":"CVE-2026-105442","record":{"aliases":["GHSA-5q74-39hp-qp43"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM WebSphere Application Server","requires_auth":"none","summary":"Remote attackers can cause denial of service in IBM WebSphere Application Server via insecure deserialization in the messaging service.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/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 8.5, and 9.0 and IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.10 Liberty could allow a remote attacker to cause a denial of service caused by an insecure deserialization in the messaging service.","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":"Deserialization in WebSphere Application Server","id":"CVE-2026-105442","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 Liberty is affected by an improper access control","id":"CVE-2026-105443"},"packages":[],"prev":{"headline":"O2OA General url ActionUploadExcelWithUrl server-side request forgery","id":"CVE-2026-105438"},"products":["WebSphere Application Server","WebSphere Application Server - Liberty"],"published":"2026-10-13","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["IBM"]},"summary":"Remote attackers can cause denial of service in IBM WebSphere Application Server via insecure deserialization in the messaging service.","url":"https://insights.sbomify.com/CVE-2026-105442/"}
