WordPress Core is vulnerable to Stored Cross-Site Scripting via the emoji settings element in all versions up to, and including, 7.0.2 due to insufficient restrictions on submitted post content. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in posts that will execute whenever a user previews the affected post.
