The WP Popular Posts plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.4.2 via the 'context' parameter. This makes it possible for unauthenticated attackers to extract sensitive edit-context fields — including raw title, raw content body, password, meta, status, and guid — from non-public post objects such as wpblock synced patterns that WordPress core itself refuses to expose to unauthenticated callers. This is possible because the plugin's REST route is registered with a permissioncallback of returntrue and passes the caller-supplied context parameter (e.g., context=edit) directly to WPRESTPostsController::prepareitemforresponse() without invoking getitempermissionscheck() or checkreadpermission(), while the underlying query accepts an arbitrary posttype value without enforcing public or showinrest visibility flags.
