Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3429 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-services (Maven): affected all versions up to 26.5.6; no fix listed\n- org.keycloak:keycloak-services (Maven): affected all versions up to 26.5.6; no fix listed\n- keycloak (Bitnami): affected from 26.4.0; fixed in 26.4.11\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-2026-3429/ (Markdown: https://insights.sbomify.com/CVE-2026-3429/index.md)","id":"CVE-2026-3429","markdown":"https://insights.sbomify.com/CVE-2026-3429/index.md","name":"CVE-2026-3429","record":{"aliases":["BIT-keycloak-2026-3429","ECHO-a685-7f88-c69b","GHSA-8g9r-9wjw-37j4","MINI-8w2p-rqvv-j7xm","MINI-gg69-g8c9-37mv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"low_privilege","summary":"An attacker with a victim's password can bypass MFA checks to delete existing credentials and register their own, leading to full account takeover.","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":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A flaw was identified in the Account REST API of Keycloak that allows a user authenticated at a lower security level to perform sensitive actions intended only for higher-assurance sessions. Specifically, an attacker who has already obtained a victim’s password can delete the victim’s registered MFA/OTP credential without first proving possession of that factor. The attacker can then register their own MFA device, effectively taking full control of the account. This weakness undermines the intended protection provided by multi-factor authentication.","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: Improper Access Control Leading to MFA Deletion and Account Takeover in Keycloak Account REST API","id":"CVE-2026-3429","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":3,"n_references":4,"next":{"headline":"Creative Mail 1.6.5 - 1.6.9 - Unauthenticated SQLi","id":"CVE-2026-3430"},"packages":[{"ecosystem":"Bitnami","fixed":["26.4.11"],"introduced":["26.4.0"],"last_affected":[],"package":"keycloak","purl":"pkg:bitnami/keycloak","source":"BIT-keycloak-2026-3429"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["26.5.6"],"package":"org.keycloak:keycloak-services","purl":null,"source":"GHSA-8g9r-9wjw-37j4"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["26.5.6"],"package":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","source":"GHSA-8g9r-9wjw-37j4"}],"prev":{"headline":"Race condition in Member Center(华硕大厅)","id":"CVE-2026-3428"},"products":["Red Hat Build of Keycloak","Red Hat JBoss Enterprise Application Platform 8","Red Hat JBoss Enterprise Application Platform Expansion Pack","Red Hat Single Sign-On 7","Red Hat build of Keycloak 26.4","Red Hat build of Keycloak 26.4.11"],"published":"2026-03-11","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":"2026-04-02","vendors":["Red Hat"]},"summary":"An attacker with a victim's password can bypass MFA checks to delete existing credentials and register their own, leading to full account takeover.","url":"https://insights.sbomify.com/CVE-2026-3429/"}
