{"id":"CVE-2026-9615","state":"PUBLISHED","title":"Flex Import <= 3.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'license_activate_fleximp' and 'license_deactivate_fleximp' AJAX Actions","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.","publishedAt":"2026-09-19T07:43:11.512Z","updatedAt":"2026-09-19T14:01:25.429Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["flextheme Flex Import"],"affected":[{"vendor":"flextheme","product":"Flex Import","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0143b789-06ea-47da-9736-3266f91a9e33?source=cve","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L86","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L93","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L159","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.8/includes/fleximp-license-functions.php#L161","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L86","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L93","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L159","https://plugins.trac.wordpress.org/browser/flex-import/tags/2.5/includes/fleximp-license-functions.php#L161","https://plugins.trac.wordpress.org/changeset?reponame=&old=3630901%40flex-import&new=3630901%40flex-import"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9615.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9615","state":"PUBLISHED","datePublished":"2026-09-19T07:43:11.512Z","dateUpdated":"2026-09-19T14:01:25.429Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-26T16:31:06.724Z"},"containers":{"cna":{"title":"Flex Import <= 3.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'license_activate_fleximp' and 'license_deactivate_fleximp' AJAX Actions","descriptions":[{"lang":"en","value":"The Flex Import plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.0.
