The WP Fastest Cache plugin for WordPress is vulnerable to unauthorized arbitrary file deletion in versions up to, and including, 0.9.0.2 due to a lack of capability checking and insufficient path validation. This makes it possible for authenticated users with minimal permissions to delete arbitrary files from the server.
An official patch is available. Apply the patch as soon as possible.
