The Editorial Calendar plugin for WordPress is vulnerable to insecure direct object reference in versions up to, and including, 3.7.12. This is due to insufficient validation on a user controlled key. This makes it possible for authenticated attackers with contributor-level capabilities and above to perform actions on objects they aren't intended to manipulate.
