Short explanation

Hugging Face Text Embeddings Inference through version 1.9.4 logs the configured api_key in cleartext because the router Args struct lacks a redact attribute, allowing unauthorized recovery of the Bearer token.

Why does it matter?

The vulnerability leads to the exposure of sensitive credentials in logs, enabling attackers to access protected endpoints.

What should be done?

  • Follow official vendor advisories and updates
  • Restrict access to log and telemetry data

Show the technical text from the sources

Hugging Face Text Embeddings Inference through 1.9.4 contains a cleartext logging vulnerability that exposes the configured api_key because the router's Args struct lacks a redact attribute for it. Attackers with access to router logs, container output, or OTLP telemetry can recover the Bearer token and call the protected embedding and rerank endpoints.
