WPshop 2 – E-Commerce 2.0.0 - 2.6.0 - Insecure Direct Object Reference to Authenticated (Subscriber+) Arbitrary User Key Generation

The WPshop 2 – E-Commerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions 2.0.0 to 2.6.0 via the callback_generate_api_key() due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create valid API keys on behalf of other users.
