According to Dangerously Set innerHTML,
Improper use of the
innerHTMLcan open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name
dangerouslySetInnerHTMLis intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key
__htmland your sanitized data as the value. Here is an example using the JSX syntax:
function createMarkup() {
return {
__html: 'First · Second' };
};
<div dangerouslySetInnerHTML={createMarkup()} />
