CVE-2026-34935

PraisonAI is a multi-agent teams system. From version 4.5.15 to before version 4.5.69, the –mcp CLI argument is passed directly to shlex.split() and forwarded through the call chain to anyio.open_process() with no validation, allowlist check, or sanitization at any hop, allowing arbitrary OS command execution as the process user. This issue has been patched in version 4.5.69.
