AI-suggested

Upgrade PraisonAI to version 4.6.34 or later, where this authentication issue has been fixed. Since this is not a cloud service, remediation requires applying the official patch by updating the product. Until the upgrade, restrict network access to the legacy Flask API server to trusted users only to mitigate unauthorized access.

Description

PraisonAI is a multi-agent teams system. From version 2.5.6 to before version 4.6.34, PraisonAI ships a legacy Flask API server with authentication disabled by default. When that server is used, any caller that can reach it can access /agents and trigger the configured agents.yaml workflow through /chat without providing a token. This issue has been patched in version 4.6.34.
