Summary
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.
Risk Assessment
An attacker with appropriate permissions can persistently inject malicious JavaScript into site pages, potentially leading to session theft, redirects, or administrator account takeover.
Recommendation
Update the plugin to a version newer than 2.4.5 as soon as it becomes available, and in the meantime limit user permissions and monitor for unusual profile changes.

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.
