CVE-2026-18037: Create by Mediavine < 2.5.4 - Unauthenticated Unpublished Content Disclosure and Publication

The Create WordPress plugin before 2.5.4 does not perform an authorization check before rendering content over one of its public REST API routes, and that route additionally publishes the requested content as a side effect, allowing unauthenticated attackers to read unpublished content and to make it publicly available.
