Booking for Appointments and Events Calendar – Amelia

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Improper Authorization in all versions up to, and including, 2.2.1. This is due to a logical short-circuit flaw in authorization logic that causes token validation to be entirely skipped when a booking has a 'waiting' status. This makes it possible for unauthenticated attackers to approve any booking that is in 'waiting' status by sending a crafted request to the publicly-accessible admin-ajax endpoint.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to, and including, 2.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform an unauthorized action.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.2. This makes it possible for unauthenticated attackers to extract sensitive user or configuration data.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.1.3. This is due to the `UpdateProviderCommandHandler` failing to validate changes to the `externalId` field when a Provider (Employee) user updates their own profile. The `externalId` maps directly to a WordPress user ID and is passed to `wp_set_password()` and `wp_update_user()` without authorization checks. This makes it possible for authenticated attackers, with Provider-level (Employee) access and above, to take over any WordPress account — including Administrator — by injecting an arbitrary `externalId` value when updating their own provider profile.

The Booking for Appointments and Events Calendar - Amelia plugin for WordPress is vulnerable to SQL Injection via the `sort` parameter in the payments listing endpoint in all versions up to, and including, 2.1.2. This is due to insufficient escaping on the user-supplied `sort` parameter and lack of sufficient preparation on the existing SQL query in `PaymentRepository.php`, where the sort field is interpolated directly into an ORDER BY clause without sanitization or whitelist validation. PDO prepared statements do not protect ORDER BY column names. GET requests also skip Amelia's nonce validation entirely. This makes it possible for authenticated attackers, with Manager-level (`wpamelia-manager`) access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via time-based blind SQL injection.

The Amelia Booking plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 9.1.2. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with customer-level permissions or above to change user passwords and potentially take over administrator accounts. The vulnerability is in the pro plugin, which has the same slug.

The Amelia plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 2.1.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom role-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2.38. This makes it possible for authenticated attackers, with employee-level access and above, to elevate their privileges to that of an administrator.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 1.2.38. This makes it possible for unauthenticated attackers to perform an unauthorized action.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to unauthorized access due to missing capability checks on multiple AJAX actions in all versions up to, and including, 1.2.38. This makes it possible for unauthenticated attackers to mark payments as refunded, trigger sending of queued notifications (emails/SMS/WhatsApp), and access debug information among other things.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to SQL Injection via the ‘search’ parameter in all versions up to, and including, 1.2.35 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 1.2.19 via the 'wpAmeliaApiCall' function. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

The Booking for Appointments and Events Calendar - Amelia plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.16 due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to perform an unauthorized action.
