Import and export users and customers vulnerabilities

The Import and export users and customers plugin in versions up to and including 2.5.2 contains a Privilege Escalation vulnerability exploitable by a Subscriber-level user. This allows privileges to be elevated.

The 'Import and export users and customers' WordPress plugin before version 2.4.2 does not enforce WordPress's role-assignment and per-user edit permissions during CSV import, allowing a user holding only the user-creation capability to create an administrator account and to overwrite an existing administrator's password or email.

The Import and export users and customers plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to and including 2.4.0. Authenticated attackers with subscriber-level access or higher can extract the post_title and raw post_content of arbitrary posts regardless of status or post type by enumerating post IDs. The required nonce is exposed as inline JavaScript on any wp-admin page when ?post_type=acui_email_template is appended to the URL, which is reachable by any authenticated user including Subscribers.
