      "value": "A missing access control check when linking banners or campaigns to a zone through the zone-include.php script of Revive Adserver 6.0.6 and earlier, or via its API allows a low‑privileged user could link their zones to banners or campaigns owned by other managers on the same instance, resulting in inconsistent ownership relationships. Ownership validation has been added to ensure that banners and campaigns can only be linked to zones managed by the same account."

      "value": "Una falta de comprobación de control de acceso al vincular banners o campañas a una zona a través del script zone-include.php de Revive Adserver 6.0.6 y anteriores, o a través de su API, permite que un usuario con pocos privilegios podría vincular sus zonas a banners o campañas propiedad de otros gestores en la misma instancia, lo que resulta en relaciones de propiedad inconsistentes. Se ha añadido validación de propiedad para asegurar que los banners y las campañas solo puedan vincularse a zonas gestionadas por la misma cuenta."
