{"id":"CVE-2026-9615","published":"2026-09-19T08:16:55.193","lastModified":"2026-09-21T13:33:33.387","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.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L159","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L161","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L86","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L93","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L159","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L161","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L86","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L93","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3630901%40flex-import&new=3630901%40flex-import","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/0143b789-06ea-47da-9736-3266f91a9e33?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
