CVE-2026-57139 Details
Description
PraisonAI is a multi-agent teams system. From 1.5.0 until 1.7.2, MCPServer.startHttp() in src/praisonai-ts/src/mcp/server.ts binds without a host restriction and forwards every HTTP POST request to handleRequest() without authentication or authorization. Any network client that can reach the port can call tools/list, tools/call, resources/read, or prompts/get, causing registered handlers to run with server-side credentials and process privileges or disclose registered data. An initial remediation was released in version 1.7.2.
A vulnerability exists in the PraisonAI npm package, specifically in versions 1.5.0 through 1.7.1, within the MCPServer component. The issue arises because the server's HTTP transport lacks authentication and authorization, allowing any network client to access sensitive MCP methods such as 'tools/call', 'resources/read', and 'prompts/get'. This is possible because the server binds to all network interfaces without host restrictions, exposing these functionalities to unauthorized users.
Users can update to PraisonAI version 1.7.2 or later, where this vulnerability has been patched. The updated version requires an authentication token for the HTTP transport, which can be set in the MCPServer configuration or via an environment variable.
