Description
The Subscribe to Comments plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.3.2 via the 'subscribe without commenting' feature, which does not check whether a post is publicly viewable. This makes it possible for unauthenticated attackers to subscribe to private or password-protected posts and receive their titles and new comments by e-mail.
