Description

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. `.QuerySet.order_by()` is subject to SQL injection in column aliases containing periods when the same alias is, using a suitably crafted dictionary, with dictionary expansion, used in `FilteredRelation`.
