Unpublished content disclosure and publication via print route
Published Aug 9, 2026 · Updated Aug 9, 2026
Missing authorization in Create before 2.5.4 allows remote attackers to read and publish unpublished cards through a public REST route. The /mv-create/v1/creations/{id}/print route renders a card selected by a sequential identifier without a nonce or permission check and changes its stored state to published. The plugin must be active with an unpublished card, and REST API reachability is sufficient; no account, cookie, nonce, or user interaction is required.
