Security Misconfiguration (CWE-306): Missing Authentication for Critical Function

Reachability: External · Exploitability: Moderate

Restrict unauthenticated E2E service exposure. These four compaction fixtures disable authentication, while both Compose files publish port 8080 on all host interfaces. Bind the published ports to 127.0.0.1:8080:8080, or enable authentication for these fixtures.

ogx-client 1.2.5 AsyncOgxClient api_key base_url Authorization header

💡 Result:

In the ogx-client Python SDK (specifically versions 1.1.4 and later, which include the 1.2.5 release), the AsyncOgxClient is used for asynchronous operations [1]. Authentication and Configuration The client automatically manages the Authorization header using an API key [1]. API Key: When you provide an api_key, the client automatically sets an Authorization: Bearer <api_key> header [1][2]. You can provide this in two ways: 1. Constructor argument: AsyncOgxClient(api_key="your-api-key") [1][3] 2. Environment variable: Set the OGX_CLIENT_API_KEY environment variable [1][3]. Constructor arguments take precedence over environment variables [1][2]. Base URL: You can configure the server endpoint using the base_url parameter [1]. 1. Constructor argument: AsyncOgxClient(base_url="http://your-server:port") [1][3] 2. Environment variable: Set the OGX_CLIENT_BASE_URL environment variable [1][3]. Example Usage import asyncio from ogx_client import AsyncOgxClient async def main: # The client will use OGX_CLIENT_API_KEY and OGX_CLIENT_BASE_URL # from the environment if not provided explicitly async with AsyncOgxClient( api_key="your-api-key", base_url="http://localhost:8321") as client: models = await client.models.list if name == "main": asyncio.run(main) Key Implementation Details - Precedence: Explicit constructor arguments > environment variables > default values [2]. - Authorization: If an api_key is provided, it sets the Authorization: Bearer header [1]. This takes precedence over any Authorization header manually included in default_headers or custom headers [2]. - Migration Note: In versions 1.1.4 and later, the library streamlined how configuration is handled compared to older versions [1]. Avoid using the older configuration patterns if you are on 1.2.5 [1].

Security Misconfiguration (CWE-319): Cleartext Transmission of Sensitive Information

Reachability: Internal · Exploitability: Moderate

Use HTTPS for the OGX service. Both fixtures pass ogx.api_key to AsyncOgxClient, which sends it as a bearer token. An http:// endpoint exposes the token on the network. Configure HTTPS with certificate validation.
