decode_values/2 in lib/ash/page/keyset.ex using non_executable_binary_to_term/2 with [:safe]. That guard blocks new atoms, funs, and ports, but not a struct built from atoms already interned in a running Ash application, so a decoded %Ash.Query.Call{} expression survives and is spliced into the keyset filter as a comparison value in do_filters/4 and evaluated. Because the cursor bypasses the Ash.Expr macro, the runtime never applies the private?/public? gate that would otherwise reject it. On AshPostgres the injected fragment is inlined into the SQL query; on the ETS and Simple data layers it is evaluated in-process as an arbitrary function call.\n\nThis issue affects ash: from 1.17.0 before 3.31.3."}, {"lang": "es", "value": "Vulnerabilidad de deserializaci\u00f3n de datos no confiables en ash-project ash permite a un atacante no autenticado inyectar una expresi\u00f3n de filtro a trav\u00e9s de un cursor de paginaci\u00f3n de conjunto de claves falsificado, resultando en inyecci\u00f3n SQL o ejecuci\u00f3n de c\u00f3digo dependiendo de la capa de datos.\n\nLas acciones de lectura con paginaci\u00f3n de conjunto de claves decodifican el cursor page[:after] o page[:before] suministrado por el cliente en decode_values/2 en lib/ash/page/keyset.ex usando non_executable_binary_to_term/2 con [:safe].
