[!] Security Concern - API Endpoints

[Hydrovolter]

Security Vulnerability: Unauthenticated API Endpoints & Weak CORS Policy

Issue Description:

The API endpoints api.hydrovolter.com and status.hydrovolter.com are currently vulnerable due to:

• Lack of Authentication: Both endpoints accept POST and GET requests without requiring any form of authorization. This allows any user to interact with the API, potentially leading to unauthorized data access or manipulation.
• Permissive CORS Policy: The current CORS policy checks for hostname: localhost:5503. This is easily bypassed as any user can replicate this environment on their local machine, effectively circumventing intended cross-origin restrictions.

Impact:

This vulnerability exposes the API to potential risks, including:

• Unauthorized data retrieval.
• Data modification or deletion.
• Denial-of-service attacks.
• Potential exposure of sensitive information.

Recommendation:

• Implement robust authentication mechanisms (e.g., API keys, JWT) for all API endpoints.
• Strengthen the CORS policy to restrict access to trusted origins. Consider using a whitelist of allowed domains or implementing more granular checks.
• Conduct a full security review of all API endpoints.

Steps to Reproduce:

1. Send a POST or GET request to api.hydrovolter.com or status.hydrovolter.com without any authorization headers.
2. Observe that the request is processed successfully.
3. Set up a local server on port 5503 and send a request to the api. observe the request is also processed.
