Optional LiteLLM deployment publishes services with public default credentials #603

Affected versions: confirmed on main at commit d92819a (the project publishes no tagged release).

Summary

The supplied docker-compose-litellm.yml profile publishes PostgreSQL (port 5432) and the LiteLLM proxy (port 4000) on host ports, falling back to the fixed, documented credentials litellm_password and sk-1234 when LITELLM_DB_PASSWORD/LITELLM_MASTER_KEY are not set.

Details

POSTGRES_PASSWORD: ${LITELLM_DB_PASSWORD:-litellm_password}
ports:
  - "5432:5432"
...
environment:
  - LITELLM_MASTER_KEY=${LITELLM_MASTER_KEY:-sk-1234}
ports:
  - "4000:4000"

# litellm-config.yml
general_settings:
  database_url: postgres://litellm:litellm_password@db:5432/litellm

Impact

An operator who starts this optional compose profile without supplying overrides exposes a database and an LLM-proxy admin API, reachable by anyone who can reach those ports, using credentials already published in this repository.

Suggested fix: remove the fallbacks (fail startup unless strong secrets are supplied) and keep both ports off the public interface. A fix is included in the linked PR.

Fix: #598
