Potential incorrect permissions on newly created file system objects

An issue was discovered in 6.0 before 6.0.3, 5.2 before 5.2.12, and 4.2 before 4.2.29. Race condition in file-system storage and file-based cache backends in Django allows an attacker to cause file system objects to be created with incorrect permissions via concurrent requests, where one thread's temporary `umask` change affects other threads in multi-threaded environments. 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 Tarek Nakkouch for reporting this issue.

Potential SQL injection in column aliases via control characters

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. `FilteredRelation` is subject to SQL injection in column aliases via control characters, using a suitably crafted dictionary, with dictionary expansion, as the `**kwargs` passed to `QuerySet` methods `annotate()`, `aggregate()`, `extra()`, `values()`, `values_list()`, and `alias()`. 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 Solomon Kebede for reporting this issue.

Potential denial-of-service vulnerability in django.utils.text.Truncator HTML methods

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. `django.utils.text.Truncator.chars()` and `Truncator.words()` methods (with `html=True`) and the `truncatechars_html` and `truncatewords_html` template filters allow a remote attacker to cause a potential denial-of-service via crafted inputs containing a large number of unmatched HTML end tags. 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 Seokchan Yoon for reporting this issue.

Username enumeration through timing difference in mod_wsgi authentication handler

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28. The `django.contrib.auth.handlers.modwsgi.check_password()` function for authentication via `mod_wsgi` allows remote attackers to enumerate users via a timing attack. 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 Stackered for reporting this issue.

Potential denial-of-service vulnerability in XML serializer text extraction

An issue was discovered in 5.2 before 5.2.9, 5.1 before 5.1.15, and 4.2 before 4.2.27. Algorithmic complexity in `django.core.serializers.xml_serializer.getInnerText()` allows a remote attacker to cause a potential denial-of-service attack triggering CPU and memory exhaustion via specially crafted XML input processed by the XML `Deserializer`. 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 Seokchan Yoon for reporting this issue.

Potential SQL injection in FilteredRelation column aliases on PostgreSQL

An issue was discovered in 5.2 before 5.2.9, 5.1 before 5.1.15, and 4.2 before 4.2.27. `FilteredRelation` is subject to SQL injection in column aliases, using a suitably crafted dictionary, with dictionary expansion, as the `**kwargs` passed to `QuerySet.annotate()` or `QuerySet.alias()` on PostgreSQL. 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 Stackered for reporting this issue.

CVE-2025-59682

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.

CVE-2025-59681

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).
