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."}],"affected":[{"vendor":"Red Hat","product":"Red Hat build of Keycloak 26.4","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"rhbk/keycloak-operator-bundle","defaultStatus":"affected","versions":[{"version":"26.4.11-1","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:build_keycloak:26.4::el9"]},{"vendor":"Red Hat","product":"Red Hat build of Keycloak 26.4","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"rhbk/keycloak-rhel9","defaultStatus":"affected","versions":[{"version":"26.4-14","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:build_keycloak:26.4::el9"]},{"vendor":"Red Hat","product":"Red Hat build of Keycloak 26.4","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"rhbk/keycloak-rhel9-operator","defaultStatus":"affected","versions":[{"version":"26.4-14","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:build_keycloak:26.4::el9"]},{"vendor":"Red Hat","product":"Red Hat build of Keycloak 26.4.11","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"unaffected","packageName":"rhbk/keycloak-rhel9","cpes":["cpe:/a:redhat:build_keycloak:26.4::el9"]},{"vendor":"Red Hat","product":"Red Hat Build of Keycloak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"rhbk/keycloak-operator-bundle","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:"]},{"vendor":"Red Hat","product":"Red Hat Build of Keycloak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"rhbk/keycloak-rhel9-operator","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:"]},{"vendor":"Red Hat","product":"Red Hat JBoss Enterprise Application Platform 8","collectionURL":"https://access.redhat.com/jbossnetwork/restricted/listSoftware.html","packageName":"keycloak-services","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:jboss_enterprise_application_platform:8"]},{"vendor":"Red Hat","product":"Red Hat JBoss Enterprise Application Platform Expansion Pack","collectionURL":"https://access.redhat.com/jbossnetwork/restricted/listSoftware.html","packageName":"keycloak-services","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:jbosseapxp"]},{"vendor":"Red Hat","product":"Red Hat Single Sign-On 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"keycloak-services","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:red_hat_single_sign_on:7"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:6477","name":"RHSA-2026:6477","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:6478","name":"RHSA-2026:6478","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-3429","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2443771","name":"RHBZ#2443771","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-03-02T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-284","description":"Improper Access Control","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-284: Improper Access Control","workarounds":[{"lang":"en","value":"Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability."}],"timeline":[{"lang":"en","time":"2026-03-02T09:10:32.484Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-03-02T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank hamayanhamayan for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-04-02T16:39:41.284Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-12T15:43:36.951927Z","id":"CVE-2026-3429","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-12T16:19:51.996Z"}}]}}
