安全的外部链接
为何重要
A link with target="_blank" and no rel="noopener" gives the opened page access to window.opener. In older browsers it can redirect your tab to a phishing page (reverse tabnabbing).
如何修复
- Add rel="noopener" (or rel="noopener noreferrer") to external links that open a new tab.
- Modern browsers apply noopener by default, but adding it explicitly protects older ones.
