No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Cookie Consent WordPress plugin before 0.0.10 does not correctly enforce its intended administrator-only capability check on its consent-settings REST routes, so they fall back to an authentication-only gate, allowing any authenticated user such as a subscriber to update the Cookie Consent WordPress plugin before 0.0.10's consent settings and, on sites connected to the vendor's paid plan, read stored visitor consent logs.
