CVE-2026-57124

2026-09-14 CVSS v3.1

CVSS

9.8

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.

Weakness (CWE)

CWE-78 OS Command Injection

CWE-306 Missing Authentication
