This is due to the 'bookly_get_form_id' handler blindly storing the attacker-controlled 'order_id' from the submitted form_data into a new booking session, which the 'bookly_render_complete' handler then trusts to look up and return the corresponding Order's secret token without verifying that the current session created that order. This makes it possible for unauthenticated attackers to enumerate sequential order IDs, disclose other customers' order tokens, retrieve calendar/appointment information via 'bookly_add_to_calendar' and permanently delete arbitrary non-completed bookings via 'bookly_rollback_order', which cascade-deletes the customer_appointment and (when no other customers are attached) the underlying appointment.","state":0,"publishedAt":"2026-09-25T06:39:55.951+00:00","modifiedAt":"2026-09-26T22:51:19.151+00:00","affected":[{"ecosystem":"Vendor product","name":"Online Scheduling and Appointment Booking System – Bookly","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ladela\",\n                    \"product\": \"Online Scheduling and Appointment Booking System – Bookly\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"28.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d45a01e5-0e69-4d95-b609-b9002b3776da?source=cve","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L733","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L46","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L1111","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/payment/Ajax.php#L74","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/lib/base/Gateway.php#L301","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/lib/UserBookingData.php#L360","https://plugins.trac.wordpress.org/changeset?reponame=&old=3707284%40bookly-responsive-appointment-booking-tool&new=3707284%40bookly-responsive-appointment-booking-tool"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93399","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93399","identifiers":["CVE-2026-93399"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
