{"id":"CVE-2026-9795","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-9795","summary":"Keycloak has privilege escalation via improper scope mapping enforcement","details":"### Description\nA flaw was found in Keycloak's Fine-Grained Admin Permissions (FGAPv2) feature. An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the Keycloak realm.","published":"2026-07-01T21:20:38Z","modified":"2026-07-01T21:30:19.104225278Z","cvss":{"score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:N"},"epss":{"score":0.00354,"percentile":0.28445,"asOf":"2026-09-07"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","fixedVersion":"26.6.4"}],"fix":{"url":"https://github.com/keycloak/keycloak/pull/50451","label":"keycloak/keycloak#50451"},"references":[{"type":"WEB","url":"https://github.com/keycloak/keycloak/security/advisories/GHSA-32h4-44jj-c5vx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-9795"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/issues/50350"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/pull/50451"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/commit/8894c027e788904c740ff9a1a60fcfaa34a10d13"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:30049"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:30050"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:30083"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:30084"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-9795"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2482462"},{"type":"PACKAGE","url":"https://github.com/keycloak/keycloak"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-9795.json"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-01T21:30:19.104225278Z"}}
