Editor-level SSRF via undisclosed request validation flaw

Server-side request forgery in WPMU DEV Broken Link Checker 2.4.14 and earlier allows remote authenticated users to send arbitrary requests. The CNA and vendor changelog do not identify the affected handler or explain how an Editor-controlled URL bypasses request validation. Editor-level WordPress access is required; the server can be induced to contact arbitrary domains and expose data from reachable services.
