CVSS 3.1
4.3 mediumCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:NCVE-2026-3190
Medium (4.3) in redhat build of keycloak. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in org.keycloak:keycloak-server-spi-private 26.5.6.
A flaw was found in Keycloak. The User-Managed Access (UMA) 2.0 Protection API endpoint for permission tickets fails to enforce the `uma_protection` role check. This allows any authenticated user with a token issued for a resource server client, even without the `uma_protection` role, to enumerate all permission tickets in the system. This vulnerability partial leads to information disclosure.
