CVE-2026-45440

The WP Ultimate CSV Importer plugin by Smackcoders Inc. contains a vulnerability involving insertion of sensitive information into sent data, allowing retrieval of embedded sensitive data. This issue affects versions from n/a through 9.1.

The WP Ultimate CSV Importer WordPress plugin before 9.2 does not use a site-specific secret when deriving the storage location of the import logs it writes under the uploads directory, nor does it block direct access to them, allowing unauthenticated attackers to retrieve the personal data of users imported from a CSV file.

The WP Ultimate CSV Importer WordPress plugin before 9.2 does not properly validate the file types contained in an uploaded archive nor sanitise their content before storing them in a publicly served location, allowing high privilege users such as administrators to achieve Stored Cross-Site Scripting.

The WP Ultimate CSV Importer WordPress plugin before 9.0 does not properly sanitise and escape imported field values before using them in a SQL statement, which could allow high privilege users such as admin to perform SQL injection attacks.

The WP Ultimate CSV Importer plugin for WordPress up to version 8.0.1 is vulnerable to Remote Code Execution via the 'MappedFields' parameter. Missing capability checks on AJAX handlers and exposure of the plugin nonce to any authenticated user allow a Subscriber to install the Import WooCommerce add-on, persist attacker-controlled PHP expressions in MappedFields, and trigger eval() in ImportHelpers::get_meta_values().
