## Description

The Burst Statistics plugin for WordPress is vulnerable to a protection mechanism bypass via the REST API Optimizer must-use plugin in all versions up to, and including, 3.7.4, due to insufficient validation of the request when deciding that a request is a Burst REST request and other plugins can be skipped. A request whose path starts with /wp-json/burst/v1/ but carries a 'rest_route' query or form parameter, or whose path uses dot segments or percent-encoding that WordPress resolves through PATH_INFO, is sent by WordPress to a different REST route while the other plugins stay unloaded. This makes it possible for unauthenticated attackers to reach core or third-party REST routes, such as the user listing, without the plugins that restrict REST API access, on sites that use such a plugin.
