Severity
8.8 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N
Summary
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.
