An unauthenticated remote user can pass a demand-override parameter to view hidden or time-restricted events, unless the disableOverrideDemand plugin setting is active.

MEDIUM 6.3EPSS 0.51%

Does this matter?

Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.

Description

The 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.
