The CMS content trap
When your React app displays HTML from a CMS, you probably use dangerouslySetInnerHTML. The name is a warning.
The risk
Malicious JavaScript in injected content executes in the user's browser. Cookie theft, phishing redirect, data exfiltration.
The solution: DOMPurify
dangerouslySetInnerHTML={{ __html: DOMPurify.sanitize(content) }}
What we find
40% of React apps we audit use dangerouslySetInnerHTML without sanitization.
