Text from the GitHub advisories:
"A vulnerability has been identified in Bootstrap that exposes users to Cross-Site Scripting (XSS) attacks. The issue is present in the carousel component, where the data-slide and data-slide-to attributes can be exploited through the href attribute of an tag due to inadequate sanitization. This vulnerability could potentially enable attackers to execute arbitrary JavaScript within the victim's browser."

How is this a CVE!

You have to put your own hyperlink with malicious javascript on the page:

<a
    href="javascript:alert('XSS href')"
    class="left"
    role="button"
    data-slide="prev"
  >

Would sanitizing the href value in the carousel data api be a sufficient fix? If so, I could fork the repo and put a PR up.
