CVE-2026-57124 Details
Description
PraisonAI is a multi-agent teams system. Prior to 4.6.59, the default UI host applications expose POST /api/mcp/connect without mandatory authentication and accept caller-controlled command and args values that PraisonAIUI passes to StdioMCPClient to start a local process. Because the UI commands bind to 0.0.0.0 by default, a reachable unauthenticated client can execute commands as the UI service account even when the MCP handshake later fails. This vulnerability is fixed in 4.6.59.
A vulnerability in PraisonAI prior to version 4.6.59 allows for unauthenticated execution of local commands through the MCP connect API. The issue arises because the default UI host applications expose the connect endpoint without authentication, and the commands are executed as the UI service account. The vulnerability is present in versions of PraisonAI that include the MCP dependency and the UI integration, with the exception of the latest release.
Users can update to PraisonAI version 4.6.59 or later, where this vulnerability has been fixed.
