CVE-2026-57510
Full vulnerability record from the local CVENow database.
Description
SuperPlane before 0.27.0 contains a broken object-level authorization vulnerability in the CanvasService gRPC handlers that allows authenticated users with viewer-level access to one organization to access resources belonging to other organizations by supplying arbitrary canvas or queue UUIDs without organization scoping. Attackers can read cross-tenant execution history and event payloads containing sensitive secrets, write queue items and canvas events into victim organizations, delete arbitrary canvases, and disrupt automation workflows across tenant boundaries.

"value": "SuperPlane anterior a 0.27.0 contiene una vulnerabilidad de autorización a nivel de objeto defectuosa en los manejadores gRPC de CanvasService que permite a usuarios autenticados con acceso de nivel de visor a una organización acceder a recursos pertenecientes a otras organizaciones al proporcionar UUIDs de lienzo o cola arbitrarios sin alcance de organización. Los atacantes pueden leer el historial de ejecución entre inquilinos y las cargas útiles de eventos que contienen secretos sensibles, escribir elementos de cola y eventos de lienzo en organizaciones víctimas, eliminar lienzos arbitrarios y perturbar los flujos de trabajo de automatización a través de los límites de los inquilinos."
