It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-3461 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-parent (Maven): affected all versions; fixed in 14.0.0\n- org.keycloak:keycloak-parent (Maven): affected all versions; fixed in 14.0.0\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-2021-3461/ (Markdown: https://insights.sbomify.com/CVE-2021-3461/index.md)","id":"CVE-2021-3461","markdown":"https://insights.sbomify.com/CVE-2021-3461/index.md","name":"CVE-2021-3461","record":{"aliases":["GHSA-cm29-6wx7-p874"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Keycloak identity provider","requires_auth":"none","summary":"Keycloak fails to terminate user sessions when logging out via external SAML IdP with specific principal settings, allowing persistent access.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"keycloak","vendor":"redhat"},{"product":"single_sign-on","vendor":"redhat"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"A flaw was found in keycloak where keycloak may fail to logout user session if the logout request comes from external SAML identity provider and Principal Type is set to Attribute [Name].","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Keycloak insufficient session expiration","id":"CVE-2021-3461","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"redhat:keycloak","products":["redhat:keycloak","redhat:single_sign-on"],"type":"auth_bypass","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Privilege escalation in Power Management Driver for Windows 10","id":"CVE-2021-3462"},"packages":[{"ecosystem":"Maven","fixed":["14.0.0"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-parent","purl":null,"source":"GHSA-cm29-6wx7-p874"},{"ecosystem":"Maven","fixed":["14.0.0"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-parent","purl":"pkg:maven/org.keycloak/keycloak-parent","source":"GHSA-cm29-6wx7-p874"}],"prev":{"headline":"Security feature bypass in MH702x","id":"CVE-2021-3460"},"products":["keycloak"],"published":"2022-04-01","related":[{"cvss_score":10,"headline":"Keycloak vulnerable to cross-site scripting when validating URI-schemes on SAML and OIDC","id":"CVE-2022-4361","kev_date_added":null,"published":"2023-07-07"},{"cvss_score":9.8,"headline":"Keycloak vulnerable to privilege escalation on Token Exchange feature","id":"CVE-2022-1245","kev_date_added":null,"published":"2022-07-07"},{"cvss_score":9.6,"headline":"keycloak Self Stored Cross-site Scripting vulnerability","id":"CVE-2021-20195","kev_date_added":null,"published":"2021-05-28"},{"cvss_score":9.3,"headline":"Keycloak Authentication Error","id":"CVE-2019-14910","kev_date_added":null,"published":"2019-12-05"},{"cvss_score":9.3,"headline":"Keycloak Authentication Error","id":"CVE-2019-14909","kev_date_added":null,"published":"2019-12-04"},{"cvss_score":9.1,"headline":"Keycloak vulnerable to path traversal via double URL encoding","id":"CVE-2022-3782","kev_date_added":null,"published":"2023-01-11"},{"cvss_score":9.1,"headline":"keycloak vulnerable to unauthorized login via mail server setup","id":"CVE-2019-14837","kev_date_added":null,"published":"2020-01-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Keycloak fails to terminate user sessions when logging out via external SAML IdP with specific principal settings, allowing persistent access.","url":"https://insights.sbomify.com/CVE-2021-3461/"}
