This is due to the `OsSettingsController::update()` handler iterating over attacker-supplied `settings` parameters without an allowlist of permitted setting names or values, and `OsSettingsHelper::prepare_value()` performing no role allowlist validation before persisting the `default_wp_role_for_customer` setting — a restriction that exists only in the UI dropdown and is never enforced server-side. This makes it possible for authenticated attackers holding a LatePoint role with the `settings__edit` capability (such as an agent or custom role) to overwrite the default WordPress role for new customers with `administrator`, causing any subsequently self-registered LatePoint customer account to be created with full WordPress administrator privileges. Exploitation requires that a WordPress administrator has granted the `settings__edit` capability to a LatePoint agent or custom role, and that a new customer account is registered through LatePoint after the malicious setting change is persisted.","state":0,"publishedAt":"2026-10-10T05:30:57.307+00:00","modifiedAt":"2026-10-11T16:55:18.205+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:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/38870e14-2e8f-4281-adb6-4be3b1d3d2ce?source=cve","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/controllers/settings_controller.php#L469","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/settings_helper.php#L754","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/customer_helper.php#L297","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.7.3/lib/helpers/settings_helper.php#L953","https://plugins.trac.wordpress.org/changeset?reponame=&old=3728691%40latepoint&new=3728691%40latepoint"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104766","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104766","identifiers":["CVE-2026-104766"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
