The Codection Import and export users and customers plugin contains a Stored Cross-Site Scripting (XSS) vulnerability caused by improper input neutralization during web page generation. The issue affects versions from the initial release through 2.5.9.

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 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Custom Column User Meta Profile Fields in all versions up to, and including, 2.4.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Editor Privilege Escalation vulnerability in Import and export users and customers up to version 2.5.5 allows a user with the editor role to escalate privileges.

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.
