It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the \"consents\" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.\n\ud83d\udccf Published: 2023-12-14T18:01:26.005Z\n\ud83d\udccf Modified: 2025-03-15T03:33:57.850Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/errata/RHSA-2023:7854\n2. https://access.redhat.com/errata/RHSA-2023:7855\n3. https://access.redhat.com/errata/RHSA-2023:7856\n4. https://access.redhat.com/errata/RHSA-2023:7857\n5. https://access.redhat.com/errata/RHSA-2023:7858\n6. https://access.redhat.com/security/cve/CVE-2023-6563\n7. https://bugzilla.redhat.com/show_bug.cgi?id=2253308\n8. https://github.com/keycloak/keycloak/issues/13340", "creation_timestamp": "2025-03-15T03:48:56.000000Z"} 2025-03-15T03:48:56+00:00 https://db.gcve.eu/sighting/232f0499-5ead-42be-ae21-436f987ab7ba/export 2026-05-16T21:50:28.718019+00:00 cedric http://db.gcve.eu/user/cedric {"uuid": "232f0499-5ead-42be-ae21-436f987ab7ba", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "RHSA-2023:7856", "type": "seen", "source": "https://t.me/DarkWebInformer_CVEAlerts/10160", "content": "\ud83d\udd17 DarkWebInformer.com - Cyber Threat Intelligence\n\ud83d\udccc CVE ID: CVE-2023-6291\n\ud83d\udd25 CVSS Score: 7.1 (cvssV3_1, Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L)\n\ud83d\udd39 Description: A flaw was found in the redirect_uri validation logic in Keycloak.
