There's a potential security issue if the URL has not been "sanitized" to prevent JavaScript execution using `javascript:`. There are libraries such as [sanitize-url](https://www.npmjs.com/package/@braintree/sanitize-url) to help with this, but note: if you're ever doing URL sanitization on the frontend, you already have a security issue. **User-provided URLs should always be sanitized by your backend before even being saved to a database.** Then the problem is avoided for _every_ client connecting to your API, including native mobile apps. Also note that even with sanitized URLs, Vue cannot help you guarantee that they lead to safe destinations.
