CyberRota Analysis

AI-Generated

PraisonAI versions prior to 4.6.78 are vulnerable due to the default exposure of the MCP HTTP-stream transport without authentication, allowing unauthenticated clients to initialize sessions, enumerate tools, and invoke them. The lack of input validation for tool-call arguments further increases the risk of exploitation. Organizations using this software should prioritize patching to mitigate potential unauthorized access and command execution risks.

Original NVD Description

PraisonAI before 4.6.78 exposes the MCP HTTP-stream transport without authentication by default: the CLI --api-key option defaults to None, and the server only enforces Authorization/Bearer checks when an API key is configured. When an operator runs 'praisonai mcp serve --transport http-stream' without an API key, an unauthenticated client (no Authorization header, and no Origin header, which is also permitted) can initialize a session, enumerate the available tools (tools/list), and invoke tools (tools/call). Additionally, the dispatcher forwards tool-call arguments to handlers without validating them against the advertised inputSchema. The server binds to 127.0.0.1 by default, so remote exploitation requires the operator to bind to a network-accessible address (e.g., --host 0.0.0.0).
