{"id":"CVE-2026-103366","state":"PUBLISHED","title":"Appointment Booking Plugin <= 5.7.3 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'booking[id]' and 'cart[id]' Parameters","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.","publishedAt":"2026-10-14T07:43:31.890Z","updatedAt":"2026-10-15T16:43:49.470Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["latepoint Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress"],"affected":[{"vendor":"latepoint","product":"Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.7.3","versionType":"semver"}]}],"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"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/103xxx/CVE-2026-103366.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-103366","state":"PUBLISHED","datePublished":"2026-10-14T07:43:31.890Z","dateUpdated":"2026-10-15T16:43:49.470Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-30T12:59:59.590Z"},"containers":{"cna":{"title":"Appointment Booking Plugin <= 5.7.3 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'booking[id]' and 'cart[id]' Parameters","descriptions":[{"lang":"en","value":"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).
