Can you explain this vulnerability to me?
The vulnerability exists in sf-mcp-server, which is an implementation of the Salesforce MCP server for Claude for Desktop. It arises from unsafe use of the child_process.exec function when constructing Salesforce CLI commands using user-controlled input. This unsafe practice allows an attacker to inject and execute arbitrary shell commands with the privileges of the MCP server process.
How can this vulnerability impact me? :
Successful exploitation of this vulnerability allows attackers to execute arbitrary shell commands on the affected system with the same privileges as the MCP server process. This can lead to unauthorized access, data compromise, system manipulation, or disruption of services.
