Description
The WP Private Message plugin for WordPress is vulnerable to insecure direct object reference in versions up to, and including, 1.0.6. This is due to insufficient validation on a user-controlled key identifying private messages between users. This makes it possible for authenticated attackers with subscriber-level capabilities and above to read arbitrary messages.
