Summary

The Flex Import plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 3.0 due to the license_activate_fleximp() and license_deactivate_fleximp() functions, hooked to AJAX actions, lacking both a capability check and nonce verification. This allows authenticated attackers with subscriber-level access and above to activate an arbitrary/fraudulent license key or deactivate the site's legitimate license, disrupting the plugin's premium functionality.

Risk Assessment

The risk includes disruption of premium functionality, potential use of fraudulent licenses, and loss of trust in the plugin.

Recommendation

It is recommended to update the plugin to the latest version and implement proper capability checks and nonce verification.

Original NVD description (English source)

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.
