Technical details
The vulnerability is an insecure direct object reference (IDOR) and authorization bypass in the Eventin plugin's REST API endpoints `/eventin/v2/customers` and `/eventin/v2/customers/{id}`. The plugin fails to enforce proper access control checks, allowing any authenticated user with Contributor role or above to enumerate and retrieve all stored customer records via REST API requests. The vulnerability requires authentication (Contributor-level account or above) and network access to the REST API. Attackers can exploit this by making authenticated REST API calls to read sensitive customer data such as names and email addresses. The issue was patched in version 4.1.20.
