AI-suggested

Upgrade PraisonAI to version 4.5.97 or later, where this vulnerability is patched by adding authentication to the Gateway server endpoints. Since the vendor has released a fixed version, applying this official update is the recommended remediation. No other mitigation guidance is provided or required based on the available data.

Description

PraisonAI is a multi-agent teams system. Prior to version 4.5.97, the PraisonAI Gateway server accepts WebSocket connections at /ws and serves agent topology at /info with no authentication. Any network client can connect, enumerate registered agents, and send arbitrary messages to agents and their tool sets. This issue has been patched in version 4.5.97.
