DescriptionThe extension fails to enforce enable-field restrictions on a repository query parameter. An unauthenticated remote user can pass a demand-override parameter to view hidden or time-restricted events, unless the disableOverrideDemand plugin setting is active. Exploitation of this issue requires only that disableOverrideDemand is not enabled.
