2026-02-03[5.2.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.

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.

2026-02-03[5.2.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.

2025-12-02[5.2.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.

The fix landed in a8cf8c292cfee98fe6cc873ca5221935f1d02271 will be backported to 5.1 and 4.2 since the 2048 limit was rolled out as part of the security release for CVE-2025-64458. Backport of 18b13cf6c48ff0a20b2a74d3b90d1fc1602608e4 from main.
2025-11-26[5.2.x] Fixed #36743 -- Increased URL max length enforced in ↵varunkasyap
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.

2025-11-24[5.2.x] Fixed #36751 -- Fixed empty filtered aggregation crash over ↵Simon Charette
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. Thanks Rafael Urben for the report, Antoliny and Youngkwang Yang for the triage. Backport of 2a6e0bd72d4a69725b957d6748a4b834f21b12b5 from main

2025-11-04[5.2.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.
