Besides security, you should also be aware of intellectual property issues. Most content is copyrighted, offline and online, even content you might not expect for example, most images on Wikimedia Commons.

Never display content on your webpage unless you own it or the owners have given you written, unequivocal permission. Penalties for copyright infringement are severe.

One important note is that you should never add both allow-scripts and allow-same-origin to your sandbox attribute — in that case, the embedded content could bypass the Same-origin policy that stops sites from executing scripts, and use JavaScript to turn off sandboxing altogether. Note: Sandboxing provides no protection if attackers can fool people into visiting malicious content directly outside an iframe.
