Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The praisonai npm package before 1.7.3 runs its AgentOS server by default on all network interfaces with no API key and wildcard CORS with credentials, so the auth check is skipped. Any network peer can, without credentials, read agent metadata and instructions from GET /api/agents and invoke agents through POST /api/chat. Upgrade to praisonai 1.7.3 or later, which is the fixed version listed, and set an API key when serving AgentOS.
