Djangoproject: >> Django >> 4.2.24 Security Vulnerabilities
An issue was discovered in 5.1 before 5.1.14, 4.2 before 4.2.26, and 5.2 before 5.2.8.
The methods `QuerySet.filter()`, `QuerySet.exclude()`, and `QuerySet.get()`, and the class `Q()`, are subject to SQL injection when using a suitably crafted dictionary, with dictionary expansion, as the `_connector` argument.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank cyberstan for reporting this issue.

NFKC normalization in Python is slow on Windows. As a consequence, `django.http.HttpResponseRedirect`, `django.http.HttpResponsePermanentRedirect`, and the shortcut `django.shortcuts.redirect` were subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.

An issue was discovered in Django 4.2 before 4.2.25, 5.1 before 5.1.13, and 5.2 before 5.2.7. The django.utils.archive.extract() function, used by the "startapp --template" and "startproject --template" commands, allows partial directory traversal via an archive with file paths sharing a common prefix with the target directory.

An issue was discovered in Django 4.2 before 4.2.25, 5.1 before 5.1.13, and 5.2 before 5.2.7. QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() are subject to SQL injection in column aliases, when using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to these methods (on MySQL and MariaDB).
