Description

The CoCart WordPress plugin before 4.9.7 does not scope its REST API authentication filter to its own endpoints, which disables WordPress core's REST nonce protection for every route, allowing an attacker to perform a cross-site request forgery attack that creates a new administrator account using a logged-in administrator's session.
