CVE-2026-54307

n8n is an open source workflow automation platform. 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.

Summary		(es) 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. Esta vulnerabilidad está corregida en 1.123.55, 2.25.7 y 2.26.2.
