Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The extension resolves the targeted club record from a user-supplied request argument in its frontend edit, update, and activate actions, but performs no ownership check in any of them. An unauthenticated visitor who knows the UID of a club record can send a direct request to the update or activate action and overwrite that record, or publish one still awaiting approval, without owning it.
