# Django 6.0.7 documentation

# Django 6.0.8 release notes

August 4, 2026

Django 6.0.8 fixes one security issue with severity "high", two security issues with severity "moderate", one security issue with severity "low", and several bugs in 6.0.7.

## CVE-2026-15307: Server-side file-write and request forgery via spatial lookups

Spatial lookups allowed `str` and `dict` lookup values to be passed to `GDALRaster` when they represented rasters. Depending on the raster driver, this could write a file to disk (in some cases enabling remote code execution) or issue a network request as the Django process user. Because the admin changelist permits filtering via `lookup_allowed()`, the flaw was reachable by staff users with view permission on any registered model containing a spatial field.

The following types are now disallowed by spatial lookups:

- `dict`

- A `str` that is not a valid `GEOSGeometry`, e.g. a serialized dictionary

This is a backward incompatible change. As a reminder, all untrusted user input should be validated before use. For that reason, assignments to model fields are unaffected and still accept these input types.

For guidance on how to keep using these types in spatial lookups, on validating untrusted input, and on further security considerations, see raster security considerations.

This issue has severity "high" according to the Django security policy.

## CVE-2026-15337: Potential denial-of-service vulnerability in `check_for_language()`

`check_for_language()` was subject to a potential denial-of-service attack when checking many distinct, very long language codes. Each code was used as a key in an in-memory cache, consuming process memory.

The `language` value reaches this function through the `django.views.i18n.set_language()` view (not active by default) from POST data. Since request data is limited by `DATA_UPLOAD_MAX_MEMORY_SIZE` and the cache is configured to store a maximum number of entries, the memory that could be consumed was bounded.

To mitigate this vulnerability, language codes longer than 500 characters are now rejected before the cached lookup.

This issue has severity "low" according to the Django security policy.

## CVE-2026-15830: Potential denial-of-service vulnerability via nested geometry collections

`GEOSGeometry` was subject to a potential denial-of-service attack when provided deeply nested `GEOMETRYCOLLECTION` objects, leading to a segmentation fault in GEOS. A maximum depth of 198 `GEOMETRYCOLLECTION`s is now enforced for the well-known text (WKT) format, and a maximum number of 198 `GEOMETRYCOLLECTION`s in total (breadth and depth) is enforced for well-known binary (WKB).

Lookups against spatial fields and the `GeometryField` form field were also affected.

The limit can be customized through the new `max_geom_collections` argument, available on `GEOSGeometry`, the `form field`, and the `model field`. The limit is not applied to GeoJSON inputs, as they were parsed by GDAL and are not affected.

This issue has severity "moderate" according to the Django security policy.

## CVE-2026-15920: Potential cross-site scripting via `URLField` values in the admin

The admin renders `URLField` values as clickable links on changelist views and read-only fields. The link was generated without validating the value as a safe URL, so a stored value using a potentially dangerous scheme was rendered as a link.

`URLField` values shown via `display_for_field` are now validated using `URLValidator` before a link is rendered, and displayed as plain text if validation is failed.

This issue has severity "moderate" according to the Django security policy.

## 漏洞修复

- Fixed a regression in Django 6.0 that caused `bulk_create()` to crash on databases that support returning rows from bulk inserts when a related object providing the primary key was saved after assignment (#37234).

- Added compatibility for `sqlparse` 0.5.5 (#37235).
