AI-suggested
Upgrade praisonaiagents to version 1.6.59 or later, where the issue is fixed. This update ensures that SecurityConfig authentication, origin-validation, and DNS-rebinding protections are properly enforced on the affected routes. No other mitigation is indicated by the vendor advisory.
Description
PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.59, ToolsMCPServer.run_sse and launch_tools_mcp_server bind to 0.0.0.0 and create /sse and /messages/ routes without invoking the available SecurityConfig authentication, origin-validation, or DNS-rebinding controls. Any reachable client can list and invoke registered tools, and a browser can target a local instance through DNS rebinding, with impact determined by the registered file, shell, and code-execution tools. This vulnerability is fixed in praisonaiagents 1.6.59.
