What is CVE-2026-9615?

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.
