The Broken Link Checker WordPress plugin before 2.4.2 does not validate a the link URLs before making a request to them, which could allow admin users to perform SSRF attack, for example on a multisite installation.
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.
