# Django 2.2.28 release notes

*April 11, 2022*

Django 2.2.28 fixes two security issues with severity “high” in 2.2.27.

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

[`QuerySet.annotate()`](/pt-br/4.1/ref/models/querysets/#django.db.models.query.QuerySet.annotate), [`aggregate()`](/pt-br/4.1/ref/models/querysets/#django.db.models.query.QuerySet.aggregate), and
[`extra()`](/pt-br/4.1/ref/models/querysets/#django.db.models.query.QuerySet.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()`](/pt-br/4.1/ref/models/querysets/#django.db.models.query.QuerySet.explain) method was subject to SQL injection in option names,
using a suitably crafted dictionary, with dictionary expansion, as the
`**options` argument.
