{"id":"CVE-2025-12787","state":"PUBLISHED","title":"Hydra Booking – All in One Appointment Booking System | Appointment Scheduling, Booking Calendar & WooCommerce Bookings <= 1.1.27 - Unauthenticated Arbitrary Booking Cancellation via Weak Hash Generation","description":"The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to unauthorized booking cancellation in all versions up to, and including, 1.1.27. This is due to the plugin's \"tfhb_meeting_form_submit_callback\" function using insufficiently random values to generate booking cancellation tokens, combined with a globally shared nonce. This makes it possible for unauthenticated attackers to cancel arbitrary bookings via brute force attacks against the tfhb_meeting_form_cencel AJAX endpoint.","publishedAt":"2025-11-11T11:03:45.316Z","updatedAt":"2026-04-08T16:50:23.131Z","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":["themefic Hydra Booking — Appointment Scheduling & Booking Calendar"],"affected":[{"vendor":"themefic","product":"Hydra Booking — Appointment Scheduling & Booking Calendar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.27","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/490dd84f-7c03-43c7-b4e1-167fa2b15c03?source=cve","https://plugins.trac.wordpress.org/changeset/3392864/hydra-booking/tags/1.1.28/app/Shortcode/HydraBookingShortcode.php?old=3392467&old_path=hydra-booking%2Ftags%2F1.1.27%2Fapp%2FShortcode%2FHydraBookingShortcode.php"],"weaknesses":["CWE-330"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/12xxx/CVE-2025-12787.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-12787","state":"PUBLISHED","datePublished":"2025-11-11T11:03:45.316Z","dateUpdated":"2026-04-08T16:50:23.131Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-11-05T23:23:11.777Z"},"containers":{"cna":{"title":"Hydra Booking – All in One Appointment Booking System | Appointment Scheduling, Booking Calendar & WooCommerce Bookings <= 1.1.27 - Unauthenticated Arbitrary Booking Cancellation via Weak Hash Generation","descriptions":[{"lang":"en","value":"The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to unauthorized booking cancellation in all versions up to, and including, 1.1.27.
