CVE-2025-59834: 
JavaScript vulnerability analysis and mitigation

A critical command injection vulnerability (CVE-2025-59834) was discovered in the adb-mcp MCP Server package, affecting versions <= 0.1.0. The vulnerability was disclosed on September 24, 2025, by security researcher Liran Tal. The affected package is publicly available on npm and allows users to execute Android debugging commands through a Node.js-based server implementation (GitHub Advisory).

The vulnerability stems from improper neutralization of special elements used in OS commands (CWE-78) within the MCP Server's executeAdbCommand() function. The server exposes an 'inspect_ui' tool that uses Node.js child process API exec function to execute Android debugging commands, making it unsafe when concatenated with untrusted user input. The vulnerability has received a CVSS v3.1 score of 9.8 (Critical), with attack vector: Network, attack complexity: Low, privileges required: None, and user interaction: None (GitHub Advisory).

The vulnerability enables user-initiated and remote command injection on a running MCP Server. When successfully exploited, it allows attackers to execute arbitrary commands on the host running the MCP Server, potentially leading to unauthorized access, data manipulation, and system compromise (GitHub Advisory).

The recommended mitigation is to replace the use of exec with execFile, which pins the command and provides arguments as array elements. Additionally, when handling user input that is not a command-line flag, implementers should use the -- notation to terminate commands and command-line flags, indicating that subsequent text is benign. As of the disclosure date, no patched versions are available (GitHub Advisory).
