{"id":"CVE-2026-103366","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-103366","summary":"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,…","details":"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.","published":"2026-10-14T08:17:02.417","modified":"2026-10-14T08:17:02.417","cvss":{"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"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/latepoint.php#L1072"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/steps_controller.php#L145"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/steps_controller.php#L290"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L1232"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L234"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/steps_helper.php#L3228"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/models/model.php#L580"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3728691%40latepoint&new=3728691%40latepoint"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2f13d1ac-d1b4-4802-bee2-3622e84d7482?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-14T08:17:02.417"}}
