Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The ContentPen WordPress plugin before 1.1.1 discloses its REST API key to unauthenticated users, who can then use it to create posts containing unfiltered JavaScript, leading to Stored XSS that executes in the browser of any visitor, including administrators.
