PPWP: Password Protect Pages, Posts & Full or Partial Content <= 1.9.15 - Improper Authorization To Authenticated (Contributor+) Master Password Exposure

The PPWP: Password Protect Pages, Posts & Full or Partial Content plugin for WordPress is vulnerable to unauthorized access of data due to a improper capability check on the can_access function in all versions up to, and including, 1.9.15. This makes it possible for authenticated attackers, with Contributor-level access and above, to retrieve a master-password and access any password-protected content.
