Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-7571 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 26.6.2\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 26.6.2\n- keycloak (Bitnami): affected from 26.4.0; fixed in 26.4.12\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-2026-7571/ (Markdown: https://insights.sbomify.com/CVE-2026-7571/index.md)","id":"CVE-2026-7571","markdown":"https://insights.sbomify.com/CVE-2026-7571/index.md","name":"CVE-2026-7571","record":{"aliases":["BIT-keycloak-2026-7571","ECHO-3445-2751-481d","GHSA-hq3p-w4xv-x7vp","MINI-978x-fgfc-8388","MINI-xvfj-j6fw-m8vj"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"low_privilege","summary":"Attackers can bypass implicit flow restrictions to obtain unauthorized access tokens, leading to token disclosure in logs and headers.","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":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-472","name":"External Control of Assumed-Immutable Web Parameter"}],"description":"A flaw was found in Keycloak. A low-privilege user, with knowledge of user credentials and client ID, can bypass a security control intended to disable the implicit flow in OpenID Connect (OIDC) clients. By manipulating client data during a session restart, an attacker can obtain an access token that should not be available. This vulnerability can also lead to the exposure of these access tokens in server logs, proxy logs, and HTTP Referrer headers, resulting in sensitive information disclosure.","ecosystems":["Bitnami","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: keycloak: access token disclosure and implicit flow bypass via forged client data","id":"CVE-2026-7571","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"redhat:build_of_keycloak","products":["redhat:build_of_keycloak"],"type":"security_feature_bypass","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Velociraptor EVTX Parser — Process Crash via Crafted .evtx File","id":"CVE-2026-7572"},"packages":[{"ecosystem":"Bitnami","fixed":["26.4.12"],"introduced":["26.4.0"],"last_affected":[],"package":"keycloak","purl":"pkg:bitnami/keycloak","source":"BIT-keycloak-2026-7571"},{"ecosystem":"Maven","fixed":["26.6.2"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":null,"source":"GHSA-hq3p-w4xv-x7vp"},{"ecosystem":"Maven","fixed":["26.6.2"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","source":"GHSA-hq3p-w4xv-x7vp"}],"prev":{"headline":"Quest NetVault Backup NVBUDashboard SQL Injection Remote Code Execution Vulnerability","id":"CVE-2026-7570"},"products":["Red Hat build of Keycloak 26.4","Red Hat build of Keycloak 26.4.12"],"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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2026-05-20","vendors":["Red Hat"]},"summary":"Attackers can bypass implicit flow restrictions to obtain unauthorized access tokens, leading to token disclosure in logs and headers.","url":"https://insights.sbomify.com/CVE-2026-7571/"}
