Attackers with query write permission can inject JSON structural characters to alter MongoDB queries, bypassing filters to read, modify, or delete arbitrary documents."

Los atacantes con permiso de escritura de consultas pueden inyectar caracteres estructurales JSON para alterar las consultas de MongoDB, eludiendo filtros para leer, modificar o eliminar documentos arbitrarios."
