Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-4133 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 15.1.1\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 15.1.1\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-2021-4133/ (Markdown: https://insights.sbomify.com/CVE-2021-4133/index.md)","id":"CVE-2021-4133","markdown":"https://insights.sbomify.com/CVE-2021-4133/index.md","name":"CVE-2021-4133","record":{"aliases":["GHSA-83x4-9cwr-5487","RHSA-2021:5218","RHSA-2021:5219"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"low_privilege","summary":"An attacker with any user account can create new default users via the admin API even when registration is disabled, bypassing access controls.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"keycloak","vendor":"redhat"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"A flaw was found in Keycloak in versions from 12.0.0 and before 15.1.1 which allows an attacker with any existing user account to create new default user accounts via the administrative REST API even when new user registration is disabled.","ecosystems":["Maven","Red Hat:red_hat_single_sign_on:7.5::el7","Red Hat:red_hat_single_sign_on:7.5::el8"],"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":"Improper Authorization in Keycloak","id":"CVE-2021-4133","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"redhat:keycloak","products":["redhat:keycloak"],"type":"missing_authorization","year":"2021"},"n_packages":6,"n_references":4,"next":{"headline":"Fancy Product Designer \u003c= 4.7.4 Admin+ SQL Injection","id":"CVE-2021-4134"},"packages":[{"ecosystem":"Maven","fixed":["15.1.1"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":null,"source":"GHSA-83x4-9cwr-5487"},{"ecosystem":"Maven","fixed":["15.1.1"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","source":"GHSA-83x4-9cwr-5487"},{"ecosystem":"Red Hat:red_hat_single_sign_on:7.5::el7","fixed":["0:15.0.2-3.redhat_00002.1.el7sso"],"introduced":["0"],"last_affected":[],"package":"rh-sso7-keycloak","purl":"pkg:rpm/redhat/rh-sso7-keycloak","source":"RHSA-2021:5218"},{"ecosystem":"Red Hat:red_hat_single_sign_on:7.5::el7","fixed":["0:15.0.2-3.redhat_00002.1.el7sso"],"introduced":["0"],"last_affected":[],"package":"rh-sso7-keycloak-server","purl":"pkg:rpm/redhat/rh-sso7-keycloak-server","source":"RHSA-2021:5218"},{"ecosystem":"Red Hat:red_hat_single_sign_on:7.5::el8","fixed":["0:15.0.2-3.redhat_00002.1.el8sso"],"introduced":["0"],"last_affected":[],"package":"rh-sso7-keycloak","purl":"pkg:rpm/redhat/rh-sso7-keycloak","source":"RHSA-2021:5219"},{"ecosystem":"Red Hat:red_hat_single_sign_on:7.5::el8","fixed":["0:15.0.2-3.redhat_00002.1.el8sso"],"introduced":["0"],"last_affected":[],"package":"rh-sso7-keycloak-server","purl":"pkg:rpm/redhat/rh-sso7-keycloak-server","source":"RHSA-2021:5219"}],"prev":{"headline":"Cross-site Scripting (XSS) -
