An attacker could exploit this vulnerability by convincing a user to visit an affected website by way of a specially crafted URL. This can be done through any medium that can contain URL web links that are controlled by the attacker, such as a link in an email, a link on a website, or a redirect on a website. Additionally, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit such websites.
