Description

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the SSE server in src/praisonai-agents/praisonaiagents/server/server.py does not consult ServerConfig.auth_token before handling /publish, /events, or /info requests. A network client that can reach the server can broadcast arbitrary events to connected clients and obtain server configuration and client-count information. This issue is fixed in praisonaiagents 1.6.58.
