An unauthenticated attacker could exploit this flaw by pre-creating an authentication session and tricking a victim into visiting a maliciously crafted link. By leveraging the /login-actions/restart endpoint—which processes session handles without adequate CSRF protection or cookie ownership validation—an attacker can reset the authentication flow state. This causes Single Sign-On (SSO) to authenticate the victim transparently upon clicking the link, allowing the attacker to hijack the required-action form without needing the victim's credentials. A successful exploit could lead to complete account takeover, including highly privileged administrative accounts.", "affected": [ { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.2", "packageName": "rhbk/keycloak-operator-bundle", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "26.2.16-1", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.2", "packageName": "rhbk/keycloak-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "26.2-21", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.2", "packageName": "rhbk/keycloak-rhel9-operator", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "26.2-21", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.2.16", "packageName": "rhbk/keycloak-rhel9-operator", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "unaffected", "versions": [] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.4", "packageName": "rhbk/keycloak-operator-bundle", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "26.4.12-1", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.4", "packageName": "rhbk/keycloak-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "26.4-17", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.4", "packageName": "rhbk/keycloak-rhel9-operator", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "26.4-17", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.4.12", "packageName": "rhbk/keycloak-rhel9-operator", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "unaffected", "versions": [] }, { "vendor": "Red Hat", "product": "Red Hat Single Sign-On 7.6.13", "packageName": "keycloak-services", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "unaffected", "versions": [] }, { "vendor": "Red Hat", "product": "Red Hat Single Sign-On 7.6 for RHEL 7", "packageName": "rh-sso7-keycloak", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:18.0.20-1.redhat_00001.1.el7sso", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Single Sign-On 7.6 for RHEL 8", "packageName": "rh-sso7-keycloak", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:18.0.20-1.redhat_00001.1.el8sso", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Single Sign-On 7.6 for RHEL 9", "packageName": "rh-sso7-keycloak", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:18.0.20-1.redhat_00001.1.el9sso", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "RHEL-8 based Middleware Containers", "packageName": "rh-sso-7/sso76-openshift-rhel8", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "7.6-85", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] } ] } } }
