Prior to 1.123.55, 2.25.7, and 2.26.2, a member-level user with editor access to a shared workflow could reference credentials they do not own via specific public API endpoints. Credential ownership checks were only enforced partially leading to cross-user credential access. This issue affects instances where workflow sharing is enabled and at least one workflow has been shared with a member-level user as an Editor. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2."},{"lang":"es","value":"n8n es una plataforma de automatización de flujos de trabajo de código abierto. Antes de 1.123.55, 2.25.7 y 2.26.2, un usuario de nivel miembro con acceso de editor a un flujo de trabajo compartido podía hacer referencia a credenciales que no poseía a través de puntos finales de API públicos específicos. Las comprobaciones de propiedad de credenciales solo se aplicaban parcialmente, lo que llevaba a un acceso a credenciales entre usuarios. Este problema afecta a las instancias donde el uso compartido de flujos de trabajo está habilitado y al menos un flujo de trabajo ha sido compartido con un usuario de nivel miembro como Editor.
