WordPress Core is vulnerable to Stored Cross-Site Scripting via Imgur embeds in versions 4.7 through 7.1.2 because Imgur is registered as a trusted oEmbed provider and its returned embed HTML is rendered without untrusted-provider sanitization. This makes it possible for authenticated attackers, with Contributor-level access and above, to store a crafted Imgur embed that can execute web scripts when an affected post is rendered by another user.
