2026-03-03[6.0.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[6.0.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[6.0.x] Refs CVE-2026-1312 -- Raised ValueError when FilteredRelation ↵Jacob Walls
aliases contain periods. This prevents failures at the database layer, given that aliases in the ON clause are not quoted. Systematically quoting aliases even in FilteredRelation is tracked in https://code.djangoproject.com/ticket/36795. Backport of 005d60d97c4dfb117503bdb6f2facfcaf9315d84 from main.
2026-02-03[6.0.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[6.0.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, and Jake Howard and Jacob Walls for reviews.

Regression in 94680437a45a71c70ca8bd2e68b72aa1e2eff337. Refs #27222. During INSERT operations, `field.pre_save()` is called to prepare values for db insertion. The `add` param must be `True` for `auto_now_add` fields to be populated. The regression commit passed `False`, causing `auto_now_add` fields to remain `None` when used by other fields, such as `upload_to` callables. Thanks Ran Benita for the report.

Regression in a16eedcf9c69d8a11d94cac1811018c5b996d491. The UNNEST strategy is affected by the same problem bulk_update has wrt/ to silent data truncation due to its usage of db_type which always returns a parametrized subtype. Backport of d6ae2ed868e43671afc4d433c3d8f4d27f7eb555 from main.
2025-12-31[6.0.x] Fixed #36829 -- Reverted value of ClearableFileInput.use_fieldset to ↵Johannes Maron
True. There was unresolved discussion regarding whether to set ClearableFileInput.use_fieldset to True or False when use_fieldset was introduced in Django 4.1, since the clear checkbox appears only sometimes. Although using <fieldset> is likely desirable, since the primary motivation in #35892 was just to improve markup in the admin, and a deprecation path was not provided for general form usage, future work is deferred to #36828. Regression in 4187da258fe212d494cb578a0bc2b52c4979ab95. Thanks Tim Graham, Antoliny, and David Smith for triage.

2025-12-16[6.0.x] Fixed #36800 -- Restored ManyToManyField renaming in ↵Clifford Gama
BaseDatabaseSchemaEditor.alter_field(). Regression in f9a44cc0fac653f8e0c2ab1cdfb12b2cc5c63fc2. Now that ManyToManyField is no longer concrete the decision of whether or not it should be altered, which is also relied on by field renaming, should take into consideration name changes even if it doesn't have a column associated with it, as auto-created many-to-many relationship table names are a base of it. Note that there is room for optimization here where a rename can be entirely avoided if ManyToManyField.db_table remains stable between .name changes, just like we do with Field.db_column remaining stable, but since this is a regression and meant to be backported the current patch focuses on correctness over further improvements. Thanks Josik for the report. Co-authored-by: Simon Charette <charette.s@gmail.com> Backport of 6cc1231285a20b11058143f8cb0a6b4b3999b23a from main.

2025-12-02[6.0.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.

HttpResponseRedirectBase. Refs CVE-2025-64458. The previous limit of 2048 characters reused the URLValidator constant and proved too restrictive for legitimate redirects to some third-party services. This change introduces a separate `MAX_URL_REDIRECT_LENGTH` constant (defaulting to 16384) and uses it in HttpResponseRedirectBase. Thanks Jacob Walls for report and review.

annotated queryset. Regression in b8e5a8a9a2a767f584cbe89a878a42363706f939. Refs #36404. The replace_expressions method was innapropriately dealing with falsey but not None source expressions causing them to also be potentially evaluated when __bool__ was invoked (e.g. QuerySet.__bool__ evaluates the queryset). The changes introduced in b8e5a8a9a2, which were to deal with a similar issue, surfaced the problem as aggregation over an annotated queryset requires an inlining (or pushdown) of aggregate references which is achieved through replace_expressions. In cases where an empty Q object was provided as an aggregate filter, such as when the admin facetting feature was used as reported, it would wrongly be turned into None, instead of an empty WhereNode, causing a crash at aggregate filter compilation. Note that the crash signature differed depending on whether or not the backend natively supports aggregate filtering (supports_aggregate_filter_clause) as the fallback, which makes use Case / When expressions, would result in a TypeError instead of a NoneType AttributeError.

2025-11-04[6.0.x] Fixed #36704 -- Fixed system check error for proxy model with a ↵Hal Blackburn
composite pk. Proxy models subclassing a model with a CompositePrimaryKey were incorrectly reporting check errors because the check that requires only local fields to be used in a composite pk was evaluated against the proxy subclass, which has no fields. To fix this, composite pk field checks are not evaluated against proxy subclasses, as none of the checks are applicable to proxy subclasses. This also has the benefit of not double-reporting real check errors from an invalid superclass pk. Thanks Clifford Gama for the review. Backport of 74564946c3b42a2ef7d087047e49873847a7e1d9 from main.
