CVE-2026-15574

Vllm-orchestrator-gateway: vllm-orchestrator-gateway: authorization header and full chat payloads logged at hard-coded debug default

Published Jul 13, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
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.

Analysis

AI-generated

Technical impact

The flaw in the vllm-orchestrator-gateway component causes the production binary to log every incoming authorization header and the full chat payload. This weakness, classified as CWE-538, may contain personally identifiable information and secrets, such as bearer tokens and conversation content. Because the logs are persistent, any user with access to the logs can read this sensitive information, leading to the disclosure of credentials and private content.

Affected Systems

This vulnerability affects the vllm-orchestrator-gateway component of Red Hat OpenShift AI (RHOAI). All deployments of this component are potentially impacted; no specific version range is listed, so the risk applies to all current releases unless patched.

Risk and Exploitability

The CVSS score of 7.5 indicates a moderate to high severity. The EPSS score is less than 1 %, indicating a low likelihood exploitation at this time. The vulnerability is not listed in CISA’s KEV catalog. Because the logs are accessible to anyone with logging privileges, an attacker who gains or already has such privileges can read tokens and content; therefore the attack vector is likely internal or through compromised monitoring accounts. No active exploit is reported, but the information leaking could facilitate credential theft or lateral movement.

Remediation

Vendor 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.


OpenCVE Recommended Actions

  • Set the RUST_LOG environment variable for the vllm-orchestrator-gateway component to a level higher than DEBUG, such as INFO, in the deployment configuration.
  • Restart the pods to make the new log level take effect.
  • Restrict log access to administrators only, limit users with logging privileges, and regularly audit those accounts for unauthorized access.
