Cross-origin resource sharing (CORS) is a mechanism to safely bypass the same-origin policy, that is, it allows a web page to access restricted resources from a server on a domain different than the domain that served the web page.
The introduction of React Hooks with React 16.8 in February 2019 allowed developers to manage state and lifecycle behaviors within functional components, reducing the reliance on class components. This trend aligns with the broader industry movement towards functional programming and modular design.
XMLHttpRequest (XHR) is an API in the form of a JavaScript object whose methods transmit HTTP requests from a web browser to a web server. [1] The methods allow a browser-based application to send requests to the server after page loading is complete, and receive information back. [2] XMLHttpRequest is a component of Ajax programming.
As the JavaScript code was also processing user input and rendering it in the web page content, a new sub-class of reflected XSS attacks started to appear that was called DOM-based cross-site scripting. In a DOM-based XSS attack, the malicious data does not touch the web server.
If data is sent in any other format (JSON, XML) a standard method is to issue a POST request using XMLHttpRequest with CSRF attacks prevented by Same-origin policy (SOP) and Cross-origin resource sharing (CORS); there is a technique to send arbitrary content from a simple HTML form using ENCTYPE attribute; such a fake request can be ...
The same-origin policy does not prevent the browser from making GET, OPTIONS, and TRACE requests; it only prevents the responses from being read by user code. Therefore, if an endpoint uses a one of these "safe" request methods to write information or perform an action on a user's behalf, it can be exploited by attackers.

The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. [2] Nodes can have event handlers (also known as event listeners) attached to them. Once an event is ...
