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.","publishedAt":"2026-09-09T02:27:34.017Z","updatedAt":"2026-09-09T13:55:02.316Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["arraytics Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce"],"affected":[{"vendor":"arraytics","product":"Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.1.22","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5e87a9ac-e7c6-4622-b3e5-6e17e7664317?source=cve","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.15/core/Order/OrderController.php#L1325","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.15/core/Order/OrderController.php#L733","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.15/core/Order/OrderController.php#L413","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.15/utils/locale/vars.php#L35","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.15/utils/helper.php#L4558","https://plugins.trac.wordpress.org/changeset?reponame=&old=3668637%40wp-event-solution&new=3668637%40wp-event-solution"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12956.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12956","state":"PUBLISHED","datePublished":"2026-09-09T02:27:34.017Z","dateUpdated":"2026-09-09T13:55:02.316Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-22T21:20:42.007Z"},"containers":{"cna":{"title":"Eventin <= 4.1.22 - Missing Authorization to Unauthenticated Arbitrary Order Creation and Status Manipulation via 'status' Parameter","descriptions":[{"lang":"en","value":"The WP Event Solution (Eventin) plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 4.1.22 via the create_item() handler for the /wp-json/eventin/v2/orders REST endpoint.
