WebPurify Profanity Filter <= 4.0.2 - Missing Authorization to Unauthenticated Plugin Settings Change via webpurify_save_options

The WebPurify Profanity Filter plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'webpurify_save_options' function in all versions up to, and including, 4.0.2. This makes it possible for unauthenticated attackers to change plugin settings.
