Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-8830 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 26.6.3\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 26.6.3\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-2026-8830/ (Markdown: https://insights.sbomify.com/CVE-2026-8830/index.md)","id":"CVE-2026-8830","markdown":"https://insights.sbomify.com/CVE-2026-8830/index.md","name":"CVE-2026-8830","record":{"aliases":["ECHO-6007-5dc2-524b","GHSA-g8vr-x4qh-25qg","MINI-4953-529j-crv9","MINI-fm86-vx82-x4fh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"low_privilege","summary":"Authenticated users can bypass WebAuthn security policies by manipulating client-side JavaScript, allowing non-compliant credential registration.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"build_of_keycloak","vendor":"redhat"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-603","name":"Use of Client-Side Authentication"}],"description":"A flaw was found in Keycloak. An authenticated user can bypass configured WebAuthn policies during credential registration by manipulating client-side JavaScript. This occurs because the server-side processAction() fails to validate that the newly created credential's parameters, such as public key algorithms, match the realm's configured WebAuthn policies. This could lead to the creation of credentials that do not adhere to administrative security requirements, potentially weakening the overall security posture of the system by allowing non-compliant authentication methods.","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: Policy bypass during WebAuthn credential registration via client-side JavaScript manipulation","id":"CVE-2026-8830","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"redhat:build_of_keycloak","products":["redhat:build_of_keycloak"],"type":"security_feature_bypass","year":"2026"},"n_packages":2,"n_references":6,"next":{"headline":"WPCode \u003c= 2.3.5 - Authenticated (Author+) Remote Code Execution via CPT Capability Bypass via XML-RPC wp.newPost","id":"CVE-2026-8832"},"packages":[{"ecosystem":"Maven","fixed":["26.6.3"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":null,"source":"GHSA-g8vr-x4qh-25qg"},{"ecosystem":"Maven","fixed":["26.6.3"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","source":"GHSA-g8vr-x4qh-25qg"}],"prev":{"headline":"HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities","id":"CVE-2026-8829"},"products":["Red Hat build of Keycloak 26.4","Red Hat build of Keycloak 26.4.13","Red Hat build of Keycloak 26.6","Red Hat build of Keycloak 26.6.3"],"published":"2026-05-19","related":[{"cvss_score":8.8,"headline":"Keycloak-services: keycloak-services: dcr protocol mapper type-swap policy bypass allows privilege escalation","id":"CVE-2026-15572","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.8,"headline":"Keycloak SAML Broken has Authentication Bypass by Primary Weakness","id":"CVE-2026-3047","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":8.1,"headline":"Keycloak-services: keycloak-services: authorization bypass via unnormalized uri matching in pathmatcher","id":"CVE-2026-15573","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.1,"headline":"Keycloak-services: keycloak-services: default dcr policy allows role forgery via user property mappers","id":"CVE-2026-16102","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.1,"headline":"Org.keycloak/keycloak-quarkus-server: keycloak: unauthorized access via jwt authorization grant with disabled users","id":"CVE-2026-1609","kev_date_added":null,"published":"2026-07-16"},{"cvss_score":8.1,"headline":"Org.keycloak:keycloak-services: keycloak: authentication bypass via jwt algorithm confusion","id":"CVE-2026-11800","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":8.1,"headline":"Keycloak-policy-enforcer: keycloak policy enforcer: authorization bypass via incorrect uri comparison","id":"CVE-2026-9800","kev_date_added":null,"published":"2026-06-25"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-26","vendors":["Red Hat"]},"summary":"Authenticated users can bypass WebAuthn security policies by manipulating client-side JavaScript, allowing non-compliant credential registration.","url":"https://insights.sbomify.com/CVE-2026-8830/"}
