Authorization Bypass (CWE-306): Missing Authentication for Critical Function

Reachability: External · Exploitability: Moderate

Restrict the E2E service exposure. The four fixtures disable authentication and use the noop module. Their Compose files publish 8080:8080 without a host-interface restriction, so a network peer that reaches the runner can send unauthenticated API requests. Change the mappings to 127.0.0.1:8080:8080 or enable test authentication.

ogx-client 1.2.5 AsyncOgxClient api_key authentication header source

💡 Result:

In the ogx-client Python SDK (which includes the AsyncOgxClient), providing an API key automatically configures the client to use the Authorization: Bearer authentication header [1][2]. You can provide the API key in two primary ways: 1. Constructor Argument: Pass the api_key parameter directly when initializing the client: from ogx_client import AsyncOgxClient client = AsyncOgxClient(api_key="your_api_key_here") 2. Environment Variable: Set the OGX_CLIENT_API_KEY environment variable. The SDK automatically detects this variable, which is recommended to avoid hardcoding keys in your source code [1][3][4]. Behavioral Notes: - Precedence: If both a constructor argument and the environment variable are provided, the constructor argument takes precedence [1][2]. - Header Details: When an API key is present, the SDK sets the Authorization: Bearer <api_key> header. This automatically derived header takes precedence over any Authorization header manually included in default_headers or custom headers [2]. - Manual Header Configuration: If you need to use a different authentication scheme or custom header, you can explicitly set it using the header_name and header_value parameters during initialization (e.g., header_name="Authorization", header_value="Bearer YOUR_TOKEN") [1][5].

Sensitive Data Exposure (CWE-319): Cleartext Transmission of Sensitive Information

Reachability: Internal · Exploitability: Moderate

Use HTTPS for the OGX service URL when api_key is configured. AsyncOgxClient sends the key as an Authorization: Bearer header, so these http:// URLs expose credential-bearing requests.
