CVE-2026-41497Public exploitNetwork attack vector

Host command execution via unchecked MCP commands

Published May 8, 2026 · Updated May 8, 2026

OS command injection in PraisonAI before 4.6.9 allows remote attackers to execute host commands through malicious MCP configuration. MCPHandler.parse_mcp_command() accepts an untrusted executable and arguments, then passes them to subprocess execution without inspecting inline-code flags. Exploitation requires control of an MCP server command through a malicious plugin or shared configuration, and commands run with the PraisonAI process's privileges.
