Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3621 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-2026-3621/ (Markdown: https://insights.sbomify.com/CVE-2026-3621/index.md)","id":"CVE-2026-3621","markdown":"https://insights.sbomify.com/CVE-2026-3621/index.md","name":"CVE-2026-3621","record":{"aliases":["GHSA-r6x6-g36w-q7qm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"WebSphere Liberty","requires_auth":"low_privilege","summary":"Attackers can spoof identities in IBM WebSphere Liberty if applications are deployed without authentication and authorization configured.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"websphere_application_server","vendor":"ibm"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.4 IBM WebSphere Application Server Liberty is vulnerable to identity spoofing under limited conditions when an application is deployed without authentication and authorization configured.","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 Liberty is affected by identity spoofing","id":"CVE-2026-3621","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:websphere_application_server","products":["ibm:websphere_application_server"],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Denial-of-Service Vulnerability in UPnP Component of TP Link's TL-WR841N","id":"CVE-2026-3622"},"packages":[],"prev":{"headline":"Word Replacer \u003c= 0.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Replacement' Parameter","id":"CVE-2026-3620"},"products":["WebSphere Application Server - Liberty"],"published":"2026-04-22","related":[{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2015-1920","kev_date_added":null,"published":"2015-05-20"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2013-0462","kev_date_added":null,"published":"2013-01-27"},{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2011-1377","kev_date_added":null,"published":"2012-01-15"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2010-3186","kev_date_added":null,"published":"2010-08-30"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2009-1899","kev_date_added":null,"published":"2009-06-03"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-1901","kev_date_added":null,"published":"2009-06-03"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-1172","kev_date_added":null,"published":"2009-03-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-04-24","vendors":["IBM"]},"summary":"Attackers can spoof identities in IBM WebSphere Liberty if applications are deployed without authentication and authorization configured.","url":"https://insights.sbomify.com/CVE-2026-3621/"}
