Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18570 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- keycloak (Bitnami): affected all versions; fixed in 26.7.3\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-2026-18570/ (Markdown: https://insights.sbomify.com/CVE-2026-18570/index.md)","id":"CVE-2026-18570","markdown":"https://insights.sbomify.com/CVE-2026-18570/index.md","name":"CVE-2026-18570","record":{"aliases":["BIT-keycloak-2026-18570","CLEANSTART-2026-CJ40397","GHSA-r6f5-hj4x-7mq7"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"low_privilege","summary":"Attackers can bypass client policy validation by omitting a field, granting unauthorized full scope access and role mappings in Keycloak.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"build_of_keycloak","vendor":"redhat"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A flaw was found in the full-scope-disabled client-policy executor within the keycloak-services component. This component is responsible for enforcing security policies during client registration and configuration in Red Hat Build of Keycloak. The issue occurs because the executor only validates the fullScopeAllowed field when it is explicitly provided in a request. By omitting this field, a delegated user can bypass the policy, resulting in a client created with full scope access. This allows the client to obtain tokens with unauthorized role mappings.","ecosystems":["Bitnami"],"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-services: keycloak-services: full-scope-disabled client policy validation bypass via omitted fullscopeallowed","id":"CVE-2026-18570","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"redhat:build_of_keycloak","products":["redhat:build_of_keycloak"],"type":"missing_authorization","year":"2026"},"n_packages":1,"n_references":4,"next":{"headline":"Keycloak-services: keycloak-services: fgap v2 group assignment bypass during user creation","id":"CVE-2026-18571"},"packages":[{"ecosystem":"Bitnami","fixed":["26.7.3"],"introduced":["0"],"last_affected":[],"package":"keycloak","purl":"pkg:bitnami/keycloak","source":"BIT-keycloak-2026-18570"}],"prev":{"headline":"Keycloak-services: keycloak-services: oidc backchannel logout accepts unsigned forged logout tokens","id":"CVE-2026-18569"},"products":["Red Hat Data Grid 8","Red Hat JBoss Enterprise Application Platform Expansion Pack","Red Hat Single Sign-On 7","Red Hat build of Keycloak 26.6","Red Hat build of Keycloak 26.6.7"],"published":"2026-08-02","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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-09-16","vendors":["Red Hat"]},"summary":"Attackers can bypass client policy validation by omitting a field, granting unauthorized full scope access and role mappings in Keycloak.","url":"https://insights.sbomify.com/CVE-2026-18570/"}
