Auth bypass in Cookie Consent

CVE-2026-18046

The Cookie Consent WordPress plugin before 0.0.10 does not correctly enforce its intended administrator-only capability check on the REST route that stores its geolocation service license key, so the route falls back to an authentication-only gate, allowing any authenticated user such as a subscriber to overwrite the stored key and disrupt the Cookie Consent WordPress plugin before 0.0.10's geolocation-based consent banner targeting.
