 "description": "The Subscribe to Comments plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on its settings page in all versions up to, and including, 2.3.1. This makes it possible for authenticated attackers, with Author-level access and above, to change the plugin's settings, including injecting scripts into the comment form text and setting the secret used to generate subscription-management keys.",
