Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88770 in the wild and no public exploit code.\n\nAffected product: Red Hat Build of Keycloak. 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-2026-88770/ (Markdown: https://insights.sbomify.com/CVE-2026-88770/index.md)","id":"CVE-2026-88770","markdown":"https://insights.sbomify.com/CVE-2026-88770/index.md","name":"CVE-2026-88770","record":{"aliases":["GHSA-q4q6-f3mm-hfmv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity and access management","requires_auth":"low_privilege","summary":"Attackers with active sessions can bypass brute-force account locks in Keycloak to obtain new tokens and maintain unauthorized access.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"A flaw was found in the Device Authorization Grant flow of Keycloak, an identity and access management solution. The issue occurs because the token redemption process fails to check if a user account is currently locked due to brute-force protection. If an attacker has an active session for a locked account, they can complete the device login process and receive new security tokens. This allows the attacker to maintain access to the account even when it should be temporarily disabled to prevent unauthorized entry.","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":"Keycloak-services: keycloak-services: device authorization grant issues tokens to brute-force-locked accounts","id":"CVE-2026-88770","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Citrix NetScaler Improper Input Validation","id":"CVE-2026-88771"},"packages":[],"prev":{"headline":"Improper Neutralization of Special Elements used in a Command ('Command Injection') in GitLab","id":"CVE-2026-88765"},"products":["Red Hat Build of Keycloak","Red Hat Single Sign-On 7"],"published":"2026-09-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-10","vendors":["Red Hat"]},"summary":"Attackers with active sessions can bypass brute-force account locks in Keycloak to obtain new tokens and maintain unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-88770/"}
