Kerentanan Incorrect Authorization pada redhat build of keycloak. Skor CVSS 3.1 6.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

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.
