MongoDB Server: authenticated user could bypass per-user access controls
Fix: upgrade to 8.0.28 or later (3 fixed versions below)
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.
