Description
The Expandable Paywall plugin for WordPress is vulnerable to Sensitive Information Exposure via feeds and the blog index listing in all versions up to, and including, 2.3.1. This is due to the paywall decision being made once per request from the first post in the query, and never per item in feeds or on non-singular listings such as the posts page. This makes it possible for unauthenticated attackers to read the full content of paywalled articles, for example through a full-text feed whose newest item is not paywalled, or on a blog index whose theme shows full post content.
