Node.js network import restrictions can be bypassed via data URLs, allowing arbitrary code execution; patched in July 2024 security releases.

Vulnerability

Overview

CVE-2024-22020 is a medium-severity flaw in Node.js that allows attackers to bypass network import restrictions. The root cause is that Node.js does not properly validate data URLs when enforcing network import policies, enabling non-network imports to be embedded within data URLs and executed.

Exploitation

An attacker can craft a data URL containing non-network imports and deliver it to a vulnerable Node.js application. When the application processes the data URL, the embedded imports bypass the intended network import restrictions, leading to arbitrary code execution. No special authentication or network position is required beyond the ability to supply a malicious data URL to the application.

Impact

Successful exploitation grants the attacker arbitrary code execution within the context of the Node.js process, potentially compromising the entire system. This poses a significant risk to developers and servers that rely on network import restrictions for security.

Mitigation

The Node.js project has addressed this vulnerability in the July 2024 security releases by forbidding data URLs in network imports [1][2]. Users are strongly advised to update to the latest patched versions of Node.js to mitigate the risk.
