Vulnerability Summary: Command Injection in elgentos/magento2-dev-mcp Vulnerability Overview This vulnerability exists within the component. When constructing Magento 2 CLI commands, the use of the unsafe method allows attackers to inject arbitrary shell commands. Attackers can construct command strings by providing user-controlled input, thereby executing malicious operations with the privileges of the MCP server process. Scope of Impact Affected Component: Affected Versions: Affected MCP Tools/Commands: : Interpolates , , and : Interpolates and : Interpolates , , and : Interpolates and : Interpolates : Interpolates : Interpolates , , , , and : Interpolates and : Interpolates : Interpolates and Exploitation Mechanism Since invokes shell commands, if the input contains shell metacharacters (such as , , ), these characters may be interpreted as additional commands rather than data. In the MCP environment, if parameters generated by an LLM are influenced by external content, it may trigger the execution of injected commands. Remediation The provided screenshot does not contain specific remediation code; however, based on the description, the fix should involve: 1. Avoid using or directly to process user input. 2. Perform strict validation and escaping of input parameters to prevent shell metacharacters from being interpreted. 3. Utilize safer execution methods (e.g., ) and avoid using shell parsers.
