Tina is a headless content management system. Prior to 0.2.1, the tina-markdown element in packages/@tinacms/web-components/src/tina-markdown.js assigns a rich-text node.url value directly to an anchor href without validating the URL scheme. A content author can store a link using a script-capable scheme, and a visitor who clicks the rendered link executes attacker-controlled script in the site's origin. The script can access same-origin application data and, when the visitor is an editor or administrator, may expose credentials stored by the TinaCMS admin on that origin. This issue is fixed in version 0.2.1.
