Image Buzz <= 1.0.3 - Missing Authorization to Unauthenticated Arbitrary API Key Modification via 'pixabay_api' Parameter

The Image Buzz plugin for WordPress is vulnerable to unauthorized API key modification due to missing authorization checks in all versions up to, and including, 1.0.3. This makes it possible for unauthenticated attackers to modify arbitrary API keys (Pixabay, Unsplash, Pixels) configured by site administrators via the 'pixabay_api', 'unsplash_api', or 'pixels_api' parameters.
