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.","state":0,"publishedAt":"2026-10-14T07:43:31.89+00:00","modifiedAt":"2026-10-15T16:43:49.47+00:00","affected":[{"ecosystem":"Vendor product","name":"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"latepoint\",\n                    \"product\": \"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.7.3\",\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:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/2f13d1ac-d1b4-4802-bee2-3622e84d7482?source=cve","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L1232","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L3228","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/models/model.php#L580","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/steps_controller.php#L145","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/steps_controller.php#L290","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L234","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/latepoint.php#L1072","https://plugins.trac.wordpress.org/changeset?reponame=&old=3728691%40latepoint&new=3728691%40latepoint"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103366","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103366","identifiers":["CVE-2026-103366"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
