2026-03-03[4.2.x] Fixed CVE-2026-25674 -- Prevented potentially incorrect permissions ↵Natalia
on file system object creation. This fix introduces `safe_makedirs()` in the `os` utils as a safer alternative to `os.makedirs()` that avoids umask-related race conditions in multi-threaded environments. This is a workaround for https://github.com/python/cpython/issues/86533 and the solution is based on the fix being proposed for CPython. Co-authored-by: Gregory P. Smith <68491+gpshead@users.noreply.github.com> Co-authored-by: Zackery Spytz <zspytz@gmail.com> Refs CVE-2020-24583 and #31921. Thanks Tarek Nakkouch for the report, and Jake Howard, Jacob Walls, and Shai Berger for reviews. Backport of 019e44f67a8dace67b786e2818938c8691132988 from main.
2026-03-03[4.2.x] Fixed CVE-2026-25673 -- Simplified URLField scheme detection.Natalia
This simplicaftion mitigates a potential DoS in URLField on Windows. The usage of `urlsplit()` in `URLField.to_python()` was replaced with `str.partition(":")` for URL scheme detection. On Windows, `urlsplit()` performs Unicode normalization which is slow for certain characters, making `URLField` vulnerable to DoS via specially crafted POST payloads. Thanks Seokchan Yoon for the report, and Jake Howard and Shai Berger for the review. Refs #36923.

2026-02-03[4.2.x] Fixed CVE-2026-1312 -- Protected order_by() from SQL injection via ↵Jacob Walls
aliases with periods. Before, `order_by()` treated a period in a field name as a sign that it was requested via `.extra(order_by=...)` and thus should be passed through as raw table and column names, even if `extra()` was not used. Since periods are permitted in aliases, this meant user-controlled aliases could force the `order_by()` clause to resolve to a raw table and column pair instead of the actual target field for the alias. In practice, only `FilteredRelation` was affected, as the other expressions we tested, e.g. `F`, aggressively optimize away the ordering expressions into ordinal positions, e.g. ORDER BY 2, instead of ORDER BY "table".column. Thanks Solomon Kebede for the report, and Simon Charette and Jake Howard for reviews. Backport of 69065ca869b0970dff8fdd8fafb390bf8b3bf222 from main.
2026-02-03[4.2.x] Fixed CVE-2026-1287 -- Protected against SQL injection in column ↵Jake Howard
aliases via control characters. Control characters in FilteredRelation column aliases could be used for SQL injection attacks. This affected QuerySet.annotate(), aggregate(), extra(), values(), values_list(), and alias() when using dictionary expansion with **kwargs. Thanks Solomon Kebede for the report, and Simon Charette, Jacob Walls, and Natalia Bidart for reviews. Backport of e891a84c7ef9962bfcc3b4685690219542f86a22 from main.
2026-02-03[4.2.x] Fixed CVE-2026-1285 -- Mitigated potential DoS in ↵Natalia
django.utils.text.Truncator for HTML input. The `TruncateHTMLParser` used `deque.remove()` to remove tags from the stack when processing end tags. With crafted input containing many unmatched end tags, this caused repeated full scans of the tag stack, leading to quadratic time complexity. The fix uses LIFO semantics, only removing a tag from the stack when it matches the most recently opened tag. This avoids linear scans for unmatched end tags and reduces complexity to linear time. Refs #30686 and 6ee37ada3241ed263d8d1c2901b030d964cbd161. Thanks Seokchan Yoon for the report. Backport of a33540b3e20b5d759aa8b2e4b9ca0e8edd285344 from main.

2025-12-02[4.2.x] Fixed CVE-2025-64460 -- Corrected quadratic inner text accumulation ↵Shai Berger
in XML serializer. Previously, `getInnerText()` recursively used `list.extend()` on strings, which added each character from child nodes as a separate list element. On deeply nested XML content, this caused the overall deserialization work to grow quadratically with input size, potentially allowing disproportionate CPU consumption for crafted XML. The fix separates collection of inner texts from joining them, so that each subtree is joined only once, reducing the complexity to linear in the size of the input. These changes also include a mitigation for a xml.dom.minidom performance issue. Thanks Seokchan Yoon (https://ch4n3.kr/) for report.

This branch migrates setuptools configuration from setup.py/setup.cfg to pyproject.toml. In order to ensure that the generated binary files have consistent casing (both the tarball and the wheel), setuptools version is limited to ">=61.0.0,<69.3.0". Configuration for flake8 was moved to a dedicated .flake8 file since it cannot be configured via pyproject.toml. Also, __pycache__ exclusion was removed from MANIFEST and the extras/Makefile was replaced with a simpler build command.
