Description
The Broken Link Checker plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.4.14.1 due to the roles field added to the REST API users endpoint being gated only by the HTTP Referer header rather than a capability check. This makes it possible for unauthenticated attackers to spoof the Referer header and retrieve the roles of users exposed through the REST API, aiding in identifying privileged accounts.
