Missing Authorization in Flex Import WordPress Plugin

Publication date: 2026-09-19

Last updated on: 2026-09-19

Assigner: Wordfence

Description

The Flex Import plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.0. This is due to the license_activate_fleximp() and license_deactivate_fleximp() functions, hooked to the wp_ajax_license_activate_fleximp and wp_ajax_license_deactivate_fleximp AJAX actions, lacking both a capability check (current_user_can()) and nonce verification (the client-side script sends a 'wpnonce' value but the handlers never validate it). This makes it possible for authenticated attackers, with subscriber-level access and above, to activate an arbitrary/fraudulent license key (persisting it via update_option('fleximp_is_premium') and toggling validation, suspension, and bundle status options) or deactivate the site's legitimate license (deleting the stored key and setting fleximp_validation_status to false), thereby disrupting the plugin's premium functionality.

Attack-Flow Graph

Executive Summary

The Flex Import plugin for WordPress has a vulnerability due to missing authorization checks in versions up to 3.0. The functions license_activate_fleximp() and license_deactivate_fleximp() are hooked to AJAX actions but do not verify user capabilities or validate nonces. This allows authenticated attackers with subscriber-level access or higher to activate fraudulent license keys or deactivate legitimate ones, disrupting the plugin's premium functionality.

Detection Guidance

Check WordPress installations for the Flex Import plugin versions up to 3.0. Look for unauthorized license activations or deactivations in logs. Review user roles with subscriber access or higher for suspicious activity.

Impact Analysis

If you use the Flex Import plugin, attackers could gain unauthorized control over your plugin's license status. This could lead to activation of fake licenses, disabling of premium features, or disruption of the plugin's normal operations, potentially affecting your website's functionality.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR or HIPAA as it involves unauthorized license activation/deactivation in a WordPress plugin. However, if the plugin handles sensitive data, improper access could indirectly impact compliance by exposing or disrupting data processing functions.

Mitigation Strategies

Update the Flex Import plugin to the latest version beyond 3.0. Remove unnecessary user roles with subscriber access. Monitor for unauthorized license changes and disable AJAX actions if not required.
