Authorization header and full chat payloads logged at hard-coded DEBUG default

Summary

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. In Red Hat OpenShift environments, these logs are directed to the node journal and cluster logging stack, making them accessible to any user with `pods/log` RBAC within the namespace. This persistent logging of credentials and private conversation content poses a significant risk of information disclosure. Red Hat severity: Moderate — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-538. Under investigation: Red Hat OpenShift AI (RHOAI).
