The Pz-LinkCard WordPress plugin through 2.5.1 does not prevent users from pinging arbitrary hosts via some of its shortcodes, which could allow high privilege users such as contributors to perform SSRF attacks.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
