Description
A flaw was found in the vllm-orchestrator-gateway component. The system's production binary logs all incoming authorization headers and full chat payloads, which may contain personally identifiable information (PII) and secrets, to persistent logs. This sensitive data, including bearer tokens and chat content, can be accessed by any user with logging privileges. This vulnerability leads to information disclosure, potentially allowing an attacker to harvest credentials and sensitive conversation content.

What to do
Workaround: To mitigate this issue, configure the `RUST_LOG` environment variable for the `vllm-orchestrator-gateway` component to a level higher than DEBUG, such as `INFO`. This will prevent the logging of sensitive authorization headers and full chat payloads to persistent logs. For example, set `RUST_LOG=info` in the deployment configuration. A restart of the affected pods or services is required for this change to take effect.
