8 Tools to Scan Node.js Applications for Security Vulnerability

Discover the Node.js safety vulnerability and defend it by fixing it earlier than somebody hacks your software.

There are a variety of on-line instruments that may enable you to discover the widespread safety vulnerability in PHP, WordPress, Joomla, and so on., however here is the twist! they could not be capable of detect in case your software is constructed on Node.js.

One of many current findings means that over 80% of customers discovered their Node.js software susceptible.

security scanner

These vulnerabilities, which might be of lots of of sorts at one time, are attributable to misconfiguration, outdated npm packages, and so on., and the next safety scanner ought to have the option that will help you discover the safety escape clause.

This text explains discover safety vulnerabilities in Node.js and safe them earlier than somebody hacks into your software.

I’d additionally wish to carry it to your consideration that this text focuses on instruments to discover a vulnerability. I like to recommend to confer with “The right way to safe Node.js in opposition to on-line threats” for configuring the safety safety.


Snyk is a helpful possibility for locating vulnerabilities in containers, code dependencies, and infrastructure as code. Whether or not it is improvement instruments, automation pipelines or workflow, Snyk integrates immediately!

Within the current replace, Snyk has included SPDX v3.20. The extent of element will enhance, however the variety of license detections ought to stay the identical. As well as, it helps npm lockfile v3 initiatives.

Don’t assume! It is the tip! It has quite a lot of different advantages, together with:

  • With Snyk you’re alert by receiving notifications about new vulnerabilities.
  • It should enable you to keep away from including any extra dependencies.

The enjoyable truth right here is that should you deploy your Node.js software in a container, you might also add unsafe packages. The Snyk Container CLI may help you determine a base picture that reduces the assault floor of your software.


In technical phrases, NodeJSScan is a static safety code scanner (SAST) developed particularly for Node.js. The language it’s based mostly on is Python. This device is supported by libsast, a generic SAST for safety engineers, and semgrep, an open-source and quickest static evaluation engine for locating vulnerabilities in third-party dependencies.

Node JS scan

To run nodejsscan you might have the command at hand, that’s: ./run.sh. This command permits you to run the nodejsscan net UI at

If you attain the combination, you possibly can create Slack or electronic mail alerts for vulnerability notifications.

General, it may detect vulnerabilities and make your software safer. It is determined by your sensible alternative of the device that may enable you to combat safety vulnerabilities. I’d counsel that Node JS Scan is a viable possibility.


In case you are in search of an ideal vulnerability finder, begin by constructing your belief in AuditJS. AuditJS has a particular OSS Index v3 REST API sword to determine recognized vulnerabilities. It will probably additionally find outdated package deal variations.

AuditJS helps npm, Angular, Yarn, and Bower package deal managers for initiatives with dependencies put in within the node_modules folder.


The set up course of includes a number of methods reminiscent of through npxwhich gives the least everlasting set up, and the command for that’s “npx auditjs@newest ossi”, or you possibly can select international set up, which gives essentially the most everlasting set up, and the command for that’s “npm set up -g auditjs”.

After my evaluate, I like to recommend utilizing through npx set up. International installs are usually discouraged within the Node.js neighborhood.


Detectify is one other device to search out vulnerabilities in your net software. It has not too long ago earned a reputation out there and emerged as a dependable possibility. It gives steady scanning to check your apps for the most recent vulnerabilities. It additionally helps the scheduling of scans parallel to your comfort.

I believe you may discover it a bit out of the field; you possibly can create integrations with customizable parameters and ship vital safety findings to the instruments you employ daily.

Lastly, I wish to spotlight one other function it gives: a whole overview of all vulnerabilities, no matter their asset.


MegaLinter is taken into account probably the most environment friendly instruments to keep away from technical debt, and this device helps us ship clear and productive code in order that customers can spend time on the workflow.


MegaLinter helps us observe code evaluate finest practices as the next device permits coders to routinely replace and analyze the code on every pull request. Most significantly, it helps to optimize the code evaluate course of, saving customers an enormous period of time.

Nonetheless, in relation to verifying error logs, MegaLinter helps builders apply some finest methods; In consequence, they’ll effectively execute vital code errors with none glitches.

Along with all these necessary elements, this device additionally supplies an inventory of IDE plugins that assist builders set up the required plugins to carry out numerous duties effectively.

Aside from all these many facets, one of many primary options of this device is that it’s fully open supply and free for any developer.

This device is unbiased because it doesn’t require any exterior software; it really works effectively on any CI device, and we are able to apply it to our native system as effectively. Nonetheless, this device is suitable with any programming language.

In consequence, any developer can simply swap to MegaLinter to take care of a clear and error-free coding atmosphere. Under we current an in depth video description of use the next device:

JS retired

There are a number of instruments to construct belief; right here comes the subsequent one: RetireJS. Builders want to grasp that simplifying improvement is admirable, however you might want to keep on high of safety fixes.

JS retired

The RetireJS group has a transparent understanding and imaginative and prescient to assist their customers detect recognized vulnerabilities. RetireJS relies on JavaScript, TypScript and Shell. There are a number of methods you need to use RetireJS,

  • As CLS (Command Line Scanner)
  • As GP (Grunt plugin)
  • As GT (Gulp job)
  • As an internet browser extension

Browser extension is talked about above in RetireJS how-to-use listing! The factor that must be emphasised right here is these extension scans for unsafe libraries and posting warnings on the developer panel. These small options, mixed with a number of others, make RetireJS top-of-the-line choices for locating vulnerabilities in your Node.JS software.

eslint plugin safety

Subsequent on the listing is Eslint-Plugin-Safety. It’s specifically made for Node Safety. With this device you possibly can simply discover and determine vulnerabilities. The set up course of offers you two choices: npm or yarn!

npm set up –save-dev eslint-plugin-security

yarn add –dev eslint-plugin-security

Throughout my analysis I found quite a lot of false potential threats that may evade human intervention. In any case the required check-ins, eslint-plugin-security takes a particular place due to its specialty for Node.js.

Node Safe CLI

Node-Safe CLI device is a dependable possibility for Node.js vulnerabilities. The group has developed a CLI/API that may totally analyze the dependency tree of a given native package deal.json or npm package deal and discover the loopholes within the repository.


Throughout use, nodes could seem crimson within the person interface. However I counsel you do not have to fret. This solely occurs if the package deal is marked with haswarnings or hasMinifiedCode

Node-Safe CLI gives many options, a few of that are listed under:

  • AST Evaluation – You possibly can run it on any .js/.mjs file within the packages.
  • Full Evaluation – It offers you the complete composition for every pack.
  • Robust protection – This device permits you to analyze npm packages and native node.js initiatives.

Given the general feel and appear of this device, I believe, with its means to detect and analyze vulnerabilities. Builders can proactively determine and handle potential vulnerabilities.


The above instruments enable you to scan your node.js software for a safety vulnerability so you possibly can safe it. Along with defending core Node.js functions, you must also think about using WAF to guard in opposition to on-line threats and DDoS assaults.
