{"cve":"CVE-2026-12905","nvd":{"published":"2026-08-16T05:16:45.947","modified":"2026-08-20T12:48:10.287","status":"Deferred","description":"The Bookly plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 27.7 via the appointment() method of the Mobile Staff Cabinet API (resource=appointment, action=bookly_mobile_staff_cabinet) in frontend/modules/mobile_staff_cabinet/api/handlers/Handler1_0.php. This is due to the handler loading an Appointment by the attacker-supplied params[id] without verifying that the appointment's staff_id matches the authenticated staff member, whereas sibling operations (deleteAppointment, saveAppointment, appointments list) correctly scope to $this->staff->getId() when $this->role === ROLE_STAFF. This makes it possible for authenticated attackers, with staff-level mobile cabinet access (any valid access_key token bound to a Staff entity), to read appointment details — including the internal note and the full customer_appointments collection (customer full_name, email, phone, notes, custom_fields, extras, payment_total, payment_type, payment_status) — belonging to other staff members by enumerating sequential appointment IDs.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/24.9/frontend/modules/mobile_staff_cabinet/Ajax.php#L17","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/24.9/frontend/modules/mobile_staff_cabinet/api/handlers/Handler.php#L82","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/24.9/frontend/modules/mobile_staff_cabinet/api/handlers/Handler1_0.php#L70","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/27.7/frontend/modules/mobile_staff_cabinet/Ajax.php#L17","https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/27.7/frontend/modules/mobile_staff_cabinet/api/handlers/Handler.php#L82"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-12905","score":0.00387,"percentile":0.3283,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
