This vulnerability allows remote attackers to execute arbitrary code on affected installations of aws-mcp-server. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the handling of the allowed commands list. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the MCP server. Was ZDI-CAN-27969."
