Problem 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.

Solution

Updated version 8.1.3 is available from the TYPO3 extension manager, packagist and at

https://extensions.typo3.org/extension/download/clubdirectory/8.1.3/zip

Users of the extension are advised to update the extension as soon as possible.
