CVE-2025-13372

In Django 6.1 before 6.1.2, 6.0 before 6.0.9, and 5.2 before 5.2.18, the function django.forms.models.BaseModelFormSet.save_existing_objects() used the presence of a primary key on a submitted form's instance as evidence that the instance belonged to the formset's limiting queryset. An object outside that queryset can be deleted by an authenticated user without permission on the targeted object, via forged management-form data. Models using the default AutoField primary key are not affected.

In Django 6.1 before 6.1.2, 6.0 before 6.0.9, and 5.2 before 5.2.18, an incomplete fix for CVE-2026-15307 in Django spatial lookups allows an attacker who can supply bytes values to cause the Django process to make network requests via a crafted VRT document referencing an external raster source.

In Django 6.1 before 6.1.2, 6.0 before 6.0.9, and 5.2 before 5.2.18, the function django.utils.http.parse_header_parameters() is subject to a potential denial-of-service attack due to quadratic time complexity when parsing a value with many separators inside a quoted parameter. An unauthenticated request could reach this parsing through headers such as Accept or Content-Type.

In Django 6.1 before 6.1.2, 6.0 before 6.0.9, and 5.2 before 5.2.18, the function django.utils.translation.get_supported_language_variant() is subject to a potential denial-of-service attack when processing many distinct, very long language codes, which are retained as keys in an in-memory cache and consume process memory.

Django versions before 1.8.16, 1.9.11, and 1.10.3, when DEBUG is enabled, allow remote attackers to conduct DNS rebinding attacks due to failure to validate the HTTP Host header against ALLOWED_HOSTS.

The cookie parsing code in Django before 1.8.15 and 1.9.x before 1.9.10, when used on a site with Google Analytics, allows remote attackers to bypass an intended CSRF protection mechanism by setting arbitrary cookies.

The utils.http.is_safe_url function in Django before 1.8.10 and 1.9.x before 1.9.3 allows remote attackers to redirect users to arbitrary web sites. This can lead to phishing attacks or potentially cross-site scripting (XSS) attacks via a URL containing basic authentication.

Django versions before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 are vulnerable to denial of service attacks. Attackers can exploit unique session keys to consume session store resources.

In Django versions before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2, the FilePathField, GenericIPAddressField, and IPAddressField model field classes do not properly perform type conversion. This may allow remote attackers to have unspecified impact related to 'MySQL typecasting.'

In Django 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28, a vulnerability was found in raster lookups on RasterField (PostGIS only). Remote attackers can inject SQL via the band index parameter.
