To fix the problem, we need to ensure that the window.location.href value is properly sanitized or encoded before being used in the HTML string. The best way to fix this issue is to use a library like DOMPurify to sanitize the URL. This will ensure that any potentially malicious content is removed before it is written to the document.
- Install the
DOMPurifylibrary. - Import
DOMPurifyin the file. - Use
DOMPurifyto sanitize thewindow.location.hrefbefore including it in the HTML string.
