Node.js, a popular server-side JavaScript runtime, has released version v20.3.1 (Current) with several security fixes. The release fixes nine CVEs, including high-severity issues such as Path Traversal Bypass and Bypass of Experimental Permission Model via Node.js Inspector.

The Node.js team has also updated OpenSSL to address several security vulnerabilities, including those disclosed in OpenSSL security advisories from March, April, and May 2023. Developers are encouraged to update their Node.js installations to the latest version to ensure their applications are secure.

In addition to security fixes, the release includes several bug fixes and improvements. The full list of changes can be found in the release notes.

Developers can upgrade their Node.js installations using a package manager such as npm or by downloading the latest version from the Node.js website.

Here's an example of how to use the new fs.promises API to read a file:

const { readFile } = require('fs').promises;

async function readMyFile() {
  try {
    const data = await readFile('myfile.txt', 'utf8');
    console.log(data);
  } catch (err) {
    console.error(err);
  }
}

readMyFile();

With the fs.promises API, developers can use async/await syntax to read files without the need for callbacks.

Overall, the Node.js v20.3.1 (Current) release provides important security fixes and improvements for developers using Node.js. Developers are encouraged to keep their Node.js installations up to date to ensure the security and stability of their applications.
