Prior to version 2.1.5, there is a command injection vulnerability caused by the unsanitized use of input parameters within a call to child_process.exec, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process&#39;s privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, &gt;, &amp;&amp;, etc.). An MCP Client can be instructed to execute additional actions for example via indirect prompt injection when asked to read git logs. This issue has been patched in version 2.1.5.</p> <p><strong>Affected:</strong> cyanheads git-mcp-server</p> <p>@cyanheads/git-mcp-server is an MCP server designed to interact with Git repositories.
