The endpoint's create_item_permissions_check() function only verifies a wp_rest nonce (which is leaked to every visitor through the etn-public script's localized_data_obj on every frontend page) and accepts a user-supplied 'status' value in prepare_item_for_database() with no whitelist validation. This makes it possible for unauthenticated attackers to create etn-order posts with status='completed' that are counted as sold by etn_get_sold_tickets_by_event(); because the auto-cleanup wp_schedule_single_event() in create_item() only fires for status='pending' orders, the forged completed orders persist indefinitely and exhaust ticket inventory.","published":"2026-09-09T03:17:22.000Z","lastModified":"2026-09-09T15:33:48.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00413,"percentile":0.35388,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.41%).
