The issue occurs when the parser handles a specific element called AuthorityBinding within an authentication statement. Due to an incomplete fix for a previous vulnerability, the parser can enter an infinite loop that consumes all available memory, causing the entire Keycloak service to crash and become unavailable to users.","published":"2026-11-05T17:17:37.280","modified":"2026-11-06T17:17:13.240","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:95759"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:95760"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:95762"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-110931"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2553047"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-06T17:17:13.240"}}
