Risks and challenges are an integral part of a project development cycle. Complex requirements, technical shortcomings, and security vulnerabilities add up to it, and it becomes a brainstorming delight for a software developer.


Among the other frameworks, react has garnered a prominent position and has become a preferred frontend framework among the others.


ReactJS offers some of the unique advantages over the other frontend frameworks, which includes simplification of scripting components, stable code, and time-effective rendering.

However, despite the manifold benefits that the frontend framework offers, there are various concerns regarding the react security vulnerabilities that you should know about.

In this comprehensive blog, you will learn about the challenges that are associated with ReactJs. However, by no means do we intend to project that it is a vulnerable library.

Why is reactjs a popular javascript framework for 2020 and beyond?

ReactJs was first released in the year 2013, and even in 2020, it is perceived as the present and future of the mobile app development. It holds relevance even after seven years, on the back of the advantages that it offers to the web and mobile application.

Numerous top applications are have been developed using ReactJs, which includes—Netflix, WhatsApp, Instagram, BBC, and Facebook.

If you are thinking to develop a mobile application or web application as java experts, you can select ReactJs among the other Javascript libraries for the following reasons:

Short training for even complex implementation

React is but a Javascript with a small API. As a result, there are just some of the functions that Java developers need to understand, and they can start using react for a web application.

Reusable components

Deployment of ReactJs is possible even if you, as a developer, possess a basic knowledge about the JavaScript. The developers can easily learn about all the components and can reuse it while building the application.

Quick render

Rendering is one of the most crucial aspects when it comes to the development of an application. Since the document object model holds the tree-structure, any changes made at the top layer may cause a ripple effect. In order to counter such a scenario, a virtual document object model has been introduced, which offers better rendering.

SEO friendliness

Today, everything is optimized for the search engine to read and provide the best results to users. In such a case, if the code is SEO-friendly, it can help improve the visibility of the application in the user’s space. On similar lines, the SEO-friendliness of ReactJS can help read JavaScript high volume apps.


When you weigh the flexibility of the other frontend frameworks with that of the ReactJS’s, you will find that the latter is less complicated to use. This is on the back of its modular structure. The flexibility that ReactJs has to offer stands out with huge time-saving and cost-saving instances.


What are the security vulnerabilities in reactjs?

The business trend is to go about building a react application for web platform. In this venture, numerous businessmen seek highly secured applications. In such a scenario, react comes to their rescue with its myriads of advantages and simplicity of development.

However, alongside, the developers have also identified react to hold several application security vulnerabilities. Most of the software development companies aren’t sure whether their developed react application will pass through the security standards.

Wait for something more intense!

Applications without a security pass may bring unexpectedly bad consequences, including data and security breach. In such a case, it is crucial that you have an eye on the react security vulnerabilities right from the start to avoid any security lapse and lawsuit.

So, what’s the best approach to use react and not fall for the vulnerabilities?

The best approach to securing the react application is to hire dedicated ReactJS developers, who are well-versed with the issues and know how to tackle these challenges.

If not, we have compiled a list of how you can secure a react web application.

Cross-site scripting

Among the other security vulnerabilities that a react application has to undergo, cross-site scripting is a common one. It is a client’s side of vulnerability that can turn into a grave issue for the application’s security.

This kind of attack can happen when an attacker successfully tricks a website. Once the website is tricked into executing an arbitrary JavaScript code, the security of users goes haywire.

There are basically two types of cross-site scripting attacks—reflected cross-site attack and stored cross-site attack. Reflected cross-site attack means that the attacker plants a link containing sensitive information of the user that is to be run in the browser.

On the other hand, stored cross-site scripting attack means that the attacker can access the server and data can be extracted from the web page of the client when the code is run.

What is the potential solution to avoid cross-site scripting?

In order to come to the solution, we need to take a look into the root cause of the issue. Since the cross-site scripting can only be done when the code is executed in a browser with specified instructions, you can disable markup that might hold the instructions for executing code.

If you are looking through an HTML code, this can include commands such as , ,
