CVE-2026-13057

An issue in the server’s Atlas Search integration allows an authenticated user to bypass per-user access controls. In sharded topologies, the $search and $searchMeta aggregation stages use internal routing that is normally populated only by the trusted router during sharded search planning. Due to insufficient input validation, an authenticated client can supply these fields directly.

Summary		(es) Un problema en la integración de Atlas Search del servidor permite a un usuario autenticado eludir los controles de acceso por usuario. En topologías fragmentadas, las etapas de agregación $search y $searchMeta utilizan enrutamiento interno que normalmente es poblado solo por el router de confianza durante la planificación de búsqueda fragmentada. Debido a una validación de entrada insuficiente, un cliente autenticado puede proporcionar estos campos directamente.
