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"}
