CVE-2026-7600 Details
Description
A flaw has been found in ArtMin96 yii2-mcp-server 1.0.2. This impacts the function yii_command_help/yii_execute_command of the file src/index.ts of the component MCP Interface. Executing a manipulation can lead to os command injection. The attack can be executed remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A command injection vulnerability has been identified in ArtMin96's Yii2 MCP Server version 1.0.2. The issue arises in the MCP tools 'yii_command_help' and 'yii_execute_command', where user-supplied arguments are directly concatenated into command strings and executed without proper sanitization. This flaw allows remote attackers to inject shell metacharacters and execute arbitrary OS commands with the privileges of the server process. The vulnerability could lead to a complete compromise of the host, including unauthorized data access, modification, and service disruption.
ArtMin96 has been notified of this vulnerability but has not yet responded. Until a patch is available, users are advised to restrict access to the MCP server, run it under a low-privilege account, and disable command-execution-oriented tools.
