Red Hat Data Grid 8: improper authorization
Medium6.5CVE-2026-18572 · Published Aug 2, 2026 · updated Sep 16, 2026
Keycloak provides authorization services that allow administrators to restrict access to resources based on time policies (for example, only allowing access during business hours). A flaw was discovered where a user can include a fake time value in their authorization request that overrides the actual server time. This allows the user to bypass these time-based restrictions and access protected resources at unauthorized times.
