{"schemaVersion":3,"id":"CVE-2026-103366","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 5.7.3 via the `booking[id]` and `cart[id]` parameters on the `steps__reload_booking_form_summary_panel` and `steps__start` public routes (reachable through wp_ajax_nopriv_latepoint_route_call). 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.","dates":{"published":"2026-10-14T07:43:31.890Z","modified":"2026-10-15T16:43:49.470Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00475,"percentile":0.40026,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-14T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00475,"percentile":0.40026}],"last30":[{"date":"2026-10-14T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00475,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00475,"percentile":0.40026}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-639","name":"Authorization
