DSGVO All in one for WP < 5.0 - Missing Authorization to Authenticated (Subscriber+) Settings Reset

Description

The DSGVO All in one for WP plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 4.9. This is due to the dsgvo_reset_policy_service_func() function lacking both capability checks and nonce verification while processing user-supplied parameters to reset plugin options. This makes it possible for authenticated attackers, with Subscriber-level access and above, to reset all customized privacy policy content including cookie notices, Google Analytics policies, Facebook policies, and YouTube policies to their default values.
