{"schemaVersion":3,"id":"CVE-2026-103907","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-14T07:43:35.022Z","modified":"2026-10-14T17:39:55.333Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00311,"percentile":0.22738,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-14T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00311,"percentile":0.22738}],"last30":[{"date":"2026-10-14T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00311,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00311,"percentile":0.22738}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-862","name":"Missing
