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"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-05T18:11:15.009019Z","id":"CVE-2026-15572","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-05T18:42:39.517Z"}}]}}
