Technical details
This is an Insecure Direct Object Reference (IDOR) vulnerability in the Eventin REST API endpoint `/wp-json/eventin/v2/orders/{id}`. The plugin does not perform proper access control checks on the read operation for individual order records, though write operations are correctly protected. An attacker with contributor-level or above WordPress account credentials can enumerate order identifiers and retrieve sensitive customer personally identifiable information (PII) including full names, email addresses, phone numbers, and payment method details. The vulnerability requires authentication and knowledge of valid order IDs but allows complete disclosure of customer data across all orders in the system. The issue is fixed in version 4.1.20.
