This is due to the `postValidateCustomer()` function using a loose PHP inequality operator (`!=`) to compare the session-stored one-time verification code against the attacker-supplied `verification_code` parameter — a flaw that is further exposed by the booking AJAX controller registering all its methods as `wp_ajax_nopriv_` handlers and unconditionally overriding `csrfTokenValid()` to return true, leaving the endpoint both unauthenticated and CSRF-unprotected. This makes it possible for unauthenticated attackers to bypass the phone/email ownership verification step and overwrite the name, email, phone, and address fields of any arbitrary existing Bookly customer record, redirecting that customer's booking notifications to attacker-controlled contact details. The bypass is achievable because the `json_data` input channel decodes input via `json_decode()`, which preserves real PHP types and causes the `wp_kses` filter to leave non-string values such as the JSON boolean `true` untouched; submitting `true` as the `verification_code` satisfies the loose comparison against the session's non-zero integer code (generated by `mt_rand(100000, 999999)`), causing `true != <non-zero int>` to evaluate as `false` and the guard to be bypassed.","state":0,"publishedAt":"2026-09-25T06:39:55.585+00:00","modifiedAt":"2026-09-25T10:37:28.171+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:L/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d24fa600-7698-4081-92f5-e11606928886?source=cve","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/lib/Validator.php#L276","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/lib/base/Component.php#L182","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L785","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L903","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/lib/UserBookingData.php#L638","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L1447","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/28.2/frontend/modules/booking/Ajax.php#L15","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-2026-92799","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92799","identifiers":["CVE-2026-92799"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
