Paytium: Mollie payment forms & donations <= 4.3.7 - Missing Authorization in 'create_mollie_profile'

The Paytium: Mollie payment forms & donations plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the create_mollie_profile function in versions up to, and including, 4.3.7. This makes it possible for authenticated attackers with subscriber-level access to create a mollie payment profile.
