{"id":"CVE-2026-103907","state":"PUBLISHED","title":"Jeg Kit for Elementor <= 3.2.19 - Missing Authorization to Authenticated (Subscriber+) Sensitive Information Exposure via 'jeg_find_author' AJAX Action","description":"The JNews - Jeg Elementor Kit plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on both the 'jkit_post_block' and 'jeg_find_author' AJAX actions in versions up to, and including, 3.2.19. The 'wp_ajax_jkit_post_block' handler (registered generically for every element via wp_ajax_{$element_id} in Elements_Option_Abstract::setup_hook) returns the element's full option schema — including a freshly minted wp_create_nonce('jeg_find_author') — to any authenticated caller, and the 'wp_ajax_jeg_find_author' handler then runs a WP_User_Query with the attacker-supplied 'query' wrapped in '*…*' against search_columns that include user_email, echoing the ID and display_name of every matching user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to enumerate every registered user of the site and to reconstruct arbitrary users' email addresses one character at a time by using the substring search as an oracle.","publishedAt":"2026-10-14T07:43:35.022Z","updatedAt":"2026-10-14T17:39:55.333Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["jegtheme Jeg Kit for Elementor – Powerful Addons for Elementor, Widgets & Templates for WordPress"],"affected":[{"vendor":"jegtheme","product":"Jeg Kit for Elementor – Powerful Addons for Elementor, Widgets & Templates for WordPress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.2.19","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/936186f9-185a-481e-a8df-5a2a3def9188?source=cve","https://plugins.trac.wordpress.org/browser/jeg-elementor-kit/tags/3.2.19/lib/jeg-element/includes/class/class-ajax.php#L101","https://plugins.trac.wordpress.org/browser/jeg-elementor-kit/tags/3.2.19/lib/jeg-element/includes/class/elements/class-elements-option-abstract.php#L106","https://plugins.trac.wordpress.org/browser/jeg-elementor-kit/tags/3.2.19/lib/jeg-element/includes/class/elements/class-elements-option-abstract.php#L63","https://plugins.trac.wordpress.org/changeset/3722837/jeg-elementor-kit"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/103xxx/CVE-2026-103907.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-103907","state":"PUBLISHED","datePublished":"2026-10-14T07:43:35.022Z","dateUpdated":"2026-10-14T17:39:55.333Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-01T14:16:11.232Z"},"containers":{"cna":{"title":"Jeg Kit for Elementor <= 3.2.19 - Missing Authorization to Authenticated (Subscriber+) Sensitive Information Exposure via 'jeg_find_author' AJAX Action","descriptions":[{"lang":"en","value":"The JNews - Jeg Elementor Kit plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on both the 'jkit_post_block' and 'jeg_find_author' AJAX actions in versions up to, and including, 3.2.19.
