Description

The WP2LEADS plugin for WordPress is vulnerable to unauthorized access via the wp2leads/v1/cron REST API endpoint in all versions up to, and including, 3.5.6. This is due to the permission callback returning true for any allowed action without checking an access key or the requester's capabilities. This makes it possible for unauthenticated attackers to call the 'prepare_for_transfer' action, which returns a map's stored KlickTipp API configuration, and the 'transfer' action, which forces a license re-check that updates the stored license data.
