## Technical details

The plugin disables WordPress core's nonce verification for cookie-authenticated REST API sessions across its entire API surface, creating a CSRF vulnerability. An unauthenticated attacker can craft a malicious link that, when clicked by a logged-in administrator, forges REST API requests in that administrator's session context. This allows account creation, configuration changes, and other privileged actions.
