Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Responsive Blocks WordPress plugin before 2.3.0 does not sanitise or escape some of the values submitted with its Form block before adding them to the HTML notification email sent to the site owner, allowing unauthenticated users to inject arbitrary HTML, such as phishing links, into that email.
