{"id":"BIT-keycloak-2026-18572","summary":"Keycloak-services: keycloak-services: uma claim token can override authorization time-policy evaluation attributes","details":"Keycloak provides authorization services that allow administrators to restrict access to resources based on time policies (for example, only allowing access during business hours). A flaw was discovered where a user can include a fake time value in their authorization request that overrides the actual server time. This allows the user to bypass these time-based restrictions and access protected resources at unauthorized times.","aliases":["CVE-2026-18572"],"modified":"2026-09-17T14:45:11.087372951Z","published":"2026-08-31T14:37:21.286Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:redhat:build_of_keycloak:*:*:*:*:-:*:*:*","cpe:2.3:a:keycloak:keycloak:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-18572"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2509763"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18572"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:68277"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:68278"}],"affected":[{"package":{"name":"keycloak","ecosystem":"Bitnami","purl":"pkg:bitnami/keycloak"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"26.7.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/keycloak/BIT-keycloak-2026-18572.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.9.0"}
