Description
PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, praisonai serve agents and praisonai serve unified parse --api-key but _create_agents_app() and _create_unified_app() do not install a credential check. Unauthenticated callers can reach POST /agents and POST /api/v1/agents/{id}/invoke. This issue is fixed in version 4.6.58.
