{"id":"CVE-2026-11616","state":"PUBLISHED","title":"Events Calendar for GeoDirectory <= 2.3.28 - Authenticated (Subscriber+) Privilege Escalation","description":"The Events Calendar for GeoDirectory plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 2.3.28. This is due to the ajax_ayi_action() handler  only applying strip_tags(esc_sql()) — with no allow-list — to the attacker-controlled $_POST['type'] and $_POST['postid'] values before forwarding them to update_ayi_data(), which calls update_user_meta($current_user->ID, $rsvp_args['type'], $posts). By passing type=wp_capabilities and postid=administrator, an attacker writes ['subscriber'=>true,'administrator'=>'administrator'] into their own wp_capabilities user meta; WP_User::get_role_caps() then treats the 'administrator' array key as an active role on the next request. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator.","publishedAt":"2026-06-09T07:49:56.778Z","updatedAt":"2026-06-09T13:32:19.796Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["stiofansisland Events Calendar for GeoDirectory"],"affected":[{"vendor":"stiofansisland","product":"Events Calendar for GeoDirectory","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.3.28","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/11ba187b-1fe4-4077-ad9d-a07660133e91?source=cve","https://plugins.trac.wordpress.org/browser/events-for-geodirectory/tags/2.3.28/includes/class-geodir-event-ayi.php#L357","https://plugins.trac.wordpress.org/browser/events-for-geodirectory/tags/2.3.28/includes/class-geodir-event-ayi.php#L154","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3533585%40events-for-geodirectory&new=3533585%40events-for-geodirectory&sfp_email=&sfph_mail="],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/11xxx/CVE-2026-11616.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-11616","state":"PUBLISHED","datePublished":"2026-06-09T07:49:56.778Z","dateUpdated":"2026-06-09T13:32:19.796Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-08T19:02:08.537Z"},"containers":{"cna":{"title":"Events Calendar for GeoDirectory <= 2.3.28 - Authenticated (Subscriber+) Privilege Escalation","descriptions":[{"lang":"en","value":"The Events Calendar for GeoDirectory plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 2.3.28.
