TL;DR

Affected versions of the @tiptap/extension-youtube library are vulnerable to Cross-site Scripting (XSS) due to a flaw in the getEmbedUrlFromYoutubeUrl function. An attacker can craft a response that stores a YouTube video with a URL containing /embed/, such as javascript:alert(1)//embed/, allowing arbitrary code execution in the site's origin. This vulnerability is considered low severity, as exploiting it would require the attacker to manipulate the TipTap payload in a way that bypasses the YouTube extension's setYoutubeVideo command, which already validates URLs.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
