Technical details
The vulnerability exists in Tool.class.php where the isApiKeyValid() method accepts a hard-coded development API key ("dev772277") when the Host header indicates localhost. An attacker can spoof the Host header as localhost and provide the known development key to bypass API access controls. This allows retrieval of private member data from the API without proper authentication or authorization.
