| Title | NousResearch hermes-agent 0.8.0 Unauthenticated Remote Code Execution |
|---|
| Description | The hermes-agent API server (OpenAI-compatible HTTP interface) completely disables authentication when no API_SERVER_KEY is configured, which is the default state, any unauthenticated network client can send arbitrary prompts to the agent. The agent's built-in terminal tool then executes OS commands on the host machine — achieving full Remote Code Execution (RCE) without any credentials. |
