Detection Guidance

This vulnerability can be detected by monitoring requests to the endpoint '/api/v1/download/<ID>/' where the 'ID' parameter is used to access private messages. Suspicious activity would include unauthorized access attempts to download messages belonging to other users.

To detect exploitation attempts on your system or network, you can use network monitoring or web server logs to identify unusual or unauthorized requests to this endpoint.
