 "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 subscription manager's e-mail change feature, which confirms the change through the old address instead of the new one. This makes it possible for unauthenticated attackers who can manage their own subscriptions to take over another e-mail address's subscriptions and obtain its subscription-management key.",
