The \"Allowed Protocol Mapper Types\" policy, which restricts which types of data mappers a client can use, fails to re-validate the mapper type during a client update if the mapper's configuration remains unchanged. An attacker with client registration privileges can exploit this by first registering an allowed mapper type with a malicious configuration and then swapping it for a restricted, high-privilege mapper type (such as one that hardcodes administrative roles). This allows the attacker to gain full administrative access to the Keycloak realm."}], "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": "26.4.14-1", "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": "26.4-22", "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": "26.4-22", "lessThan": "*", "versionType": "rpm", "status": "unaffected"}], "cpes": ["cpe:/a:redhat:build_keycloak:26.4::el9"]}, {"vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.4.14", "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 26.6", "collectionURL": "https://catalog.redhat.com/software/containers/", "packageName": "rhbk/keycloak-operator-bundle", "defaultStatus": "affected", "versions": [{"version": "26.6.5-1", "lessThan": "*", "versionType": "rpm", "status": "unaffected"}], "cpes": ["cpe:/a:redhat:build_keycloak:26.6::el9"]}, {"vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.6", "collectionURL": "https://catalog.redhat.com/software/containers/", "packageName": "rhbk/keycloak-rhel9", "defaultStatus": "affected", "versions": [{"version": "26.6-11", "lessThan": "*", "versionType": "rpm", "status": "unaffected"}], "cpes": ["cpe:/a:redhat:build_keycloak:26.6::el9"]}, {"vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.6", "collectionURL": "https://catalog.redhat.com/software/containers/", "packageName": "rhbk/keycloak-rhel9-operator", "defaultStatus": "affected", "versions": [{"version": "26.6-11", "lessThan": "*", "versionType": "rpm", "status": "unaffected"}], "cpes": ["cpe:/a:redhat:build_keycloak:26.6::el9"]}, {"vendor": "Red Hat", "product": "Red Hat build of Keycloak 26.6.5", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "unaffected", "packageName": "rhbk/keycloak-rhel9", "cpes": ["cpe:/a:redhat:build_keycloak:26.6::el9"]}], "references": [{"url": "https://access.redhat.com/errata/RHSA-2026:50846", "name": "RHSA-2026:50846", "tags": ["vendor-advisory", "x_refsource_REDHAT"]}, {"url": "https://access.redhat.com/errata/RHSA-2026:50847", "name": "RHSA-2026:50847", "tags": ["vendor-advisory", "x_refsource_REDHAT"]}, {"url": "https://access.redhat.com/errata/RHSA-2026:50848", "name": "RHSA-2026:50848", "tags": ["vendor-advisory", "x_refsource_REDHAT"]}, {"url": "https://access.redhat.com/errata/RHSA-2026:50849", "name": "RHSA-2026:50849", "tags": ["vendor-advisory", "x_refsource_REDHAT"]}, {"url": "https://access.redhat.com/security/cve/CVE-2026-15572", "tags": ["vdb-entry", "x_refsource_REDHAT"]}, {"url": "https://bugzilla.redhat.com/show_bug.cgi?id=2499592", "name": "RHBZ#2499592", "tags": ["issue-tracking", "x_refsource_REDHAT"]}], "datePublic": "2026-08-05T02:02:00.000Z", "problemTypes": [{"descriptions": [{"cweId": "CWE-843", "description": "Access of Resource Using Incompatible Type ('Type Confusion')", "lang": "en", "type": "CWE"}]}], "x_redhatCweChain": "CWE-843: Access of Resource Using Incompatible Type ('Type Confusion')", "timeline": [{"lang": "en", "time": "2026-07-06T23:27:45.000Z", "value": "Reported to Red Hat."}, {"lang": "en", "time": "2026-08-05T02:02:00.000Z", "value": "Made public."}], "credits": [{"lang": "en", "value": "Red Hat would like to thank Arthur Chan (Ada Logics) for reporting this issue."}], "providerMetadata": {"orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-08-05T18:11:41.062Z"}, "x_generator": {"engine": "cvelib 1.8.0"}}}}
