CVE-2026-104766 · Severity: high · CVSS 8.8 · Published 2026-10-10

LatePoint is an appointment booking plugin for WordPress that manages customer scheduling. An authenticated staff member with settings editing privileges can exploit missing input validation to change the default WordPress role assigned to newly registered customers from a standard customer role to administrator, granting those new accounts full site control. This requires both a prior configuration by a WordPress admin and a new customer registration after the attack.

## Technical details

The OsSettingsController::update() handler processes attacker-controlled settings parameters without an allowlist, and OsSettingsHelper::prepare_value() fails to validate the `default_wp_role_for_customer` setting server-side despite UI restrictions existing in the client. An authenticated LatePoint agent or custom role holding the `settings__edit` capability can inject `administrator` as the default role, escalating any subsequently registered customer to WordPress administrator. The vulnerability requires prior WordPress admin configuration granting `settings__edit` to the attacker's LatePoint role.
