April 11, 2022

Django 4.0.4 fixes two security issues with severity "high" and two bugs in 4.0.3.

## CVE-2022-28346: Potential SQL injection in `QuerySet.annotate()`, `aggregate()`, and `extra()`

`QuerySet.annotate()`, `aggregate()`, and `extra()` methods were subject to SQL injection in column aliases, using a suitably crafted dictionary, with dictionary expansion, as the `**kwargs` passed to these methods.

## CVE-2022-28347: Potential SQL injection via `QuerySet.explain(**options)` on PostgreSQL

`QuerySet.explain()` method was subject to SQL injection in option names, using a suitably crafted dictionary, with dictionary expansion, as the `**options` argument.

## Perbaikan kesalahan

- Fixed a regression in Django 4.0 that caused ignoring multiple `FilteredRelation()` relationships to the same field (#33598).
