| Doc Text: |
A flaw was found in Node.js. This vulnerability allows an attacker to cause a Denial of Service (DoS) by providing a malformed Internationalized Domain Name (IDN) to the `url.format()` function. When processed, this malformed input triggers an internal error, causing the Node.js application to crash. This can disrupt services and make them unavailable.
