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."}],"title":"Online Scheduling and Appointment Booking System – Bookly <= 27.7 - Authenticated (Staff+) Insecure Direct Object Reference to Sensitive Information Exposure via 'params[id]' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1600466e-ad45-4dc7-916b-6c97301d2b03?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/27.7/frontend/modules/mobile_staff_cabinet/api/handlers/Handler1_0.php#L70"},{"url":"https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/27.7/frontend/modules/mobile_staff_cabinet/Ajax.php#L17"},{"url":"https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/27.7/frontend/modules/mobile_staff_cabinet/api/handlers/Handler.php#L82"},{"url":"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"},{"url":"https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/24.9/frontend/modules/mobile_staff_cabinet/Ajax.php#L17"},{"url":"https://plugins.trac.wordpress.org/browser/bookly-responsive-appointment-booking-tool/tags/24.9/frontend/modules/mobile_staff_cabinet/api/handlers/Handler.php#L82"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3637918%40bookly-responsive-appointment-booking-tool&new=3637918%40bookly-responsive-appointment-booking-tool"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-639 Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Raihan Adi Arba"}],"timeline":[{"time":"2026-06-23T13:31:20.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-15T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-17T14:13:59.539599Z","id":"CVE-2026-12905","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-17T16:06:16.276Z"}}]}}
