{"id":"CVE-2025-11517","state":"PUBLISHED","title":"Event Tickets and Registration <= 5.26.5 - Unauthenticated Ticket Payment Bypass","description":"The Event Tickets and Registration plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 5.26.5. This is due to the /wp-json/tribe/tickets/v1/commerce/free/order endpoint not verifying that a ticket type should be free allowing the user to bypass the payment. This makes it possible for unauthenticated attackers to obtain access to paid tickets, without paying for them, causing a loss of revenue for the target.","publishedAt":"2025-10-18T06:42:43.892Z","updatedAt":"2026-04-08T16:41:30.638Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["stellarwp Event Tickets and Registration"],"affected":[{"vendor":"stellarwp","product":"Event Tickets and Registration","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.26.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/21cd8cb8-2a29-4b66-ab7a-8d8b2f85e2e0?source=cve","https://plugins.trac.wordpress.org/changeset/3378214/event-tickets/tags/5.26.6/src/Tickets/Commerce/Gateways/Free/REST/Order_Endpoint.php"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/11xxx/CVE-2025-11517.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-11517","state":"PUBLISHED","datePublished":"2025-10-18T06:42:43.892Z","dateUpdated":"2026-04-08T16:41:30.638Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-10-08T15:26:41.876Z"},"containers":{"cna":{"title":"Event Tickets and Registration <= 5.26.5 - Unauthenticated Ticket Payment Bypass","descriptions":[{"lang":"en","value":"The Event Tickets and Registration plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 5.26.5.
