# CVE-2026-9615: Flex Import \<= 3.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'license\_activate\_fleximp' and 'license\_deactivate\_fleximp' AJAX Actions

- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no

## Affected

- flextheme Flex Import: through 3.0

## 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.
