This is due to `OsStepsHelper::set_required_objects()` feeding raw request parameters into `set_booking_object()` and `set_cart_object()`, which call `OsModel::set_data()` and load an arbitrary booking or cart row by primary key with no ownership check — the ownership guard the vendor added for the earlier disclosure lives only inside `OsStepsHelper::load_step()` and does not cover the sibling routes or `cart[id]` at all. This makes it possible for unauthenticated attackers to enumerate sequential booking / cart identifiers and read other customers' appointment details (service name, agent, date/time, duration, price breakdown, status) and other shoppers' pending checkout contents directly from the JSON responses."}],"title":"Appointment Booking Plugin <= 5.7.3 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'booking[id]' and 'cart[id]' Parameters","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2f13d1ac-d1b4-4802-bee2-3622e84d7482?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L1232"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L3228"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/models/model.php#L580"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/steps_controller.php#L145"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/steps_controller.php#L290"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L234"},{"url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/latepoint.php#L1072"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3728691%40latepoint&new=3728691%40latepoint"}],"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:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"churchill11"}],"timeline":[{"time":"2026-09-30T13:16:23.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-13T19:19:27.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-103366","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-15T10:47:08.354377Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-15T16:43:49.470Z"}}]}}
