Django 4.0.4 release notes

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.

Bugfixes

  • Fixed a regression in Django 4.0 that caused ignoring multiple FilteredRelation() relationships to the same field (#33598).
  • Fixed a regression in Django 3.2.4 that caused the auto-reloader to no longer detect changes when the DIRS option of the TEMPLATES setting contained an empty string (#33628).
