Description

This security bulletin contains information about 4 vulnerabilities.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-77050)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

n

The vulnerability exists due to insufficient limits on memory consumption in django.utils.translation.get_supported_language_variant() when processing language codes that are cached before their length is limited. A remote attacker can supply many distinct, very long language codes to cause a denial of service.

n


2) Inefficient Algorithmic Complexity (CVE-ID: CVE-2026-84429)

CWE-ID: CWE-407 - Inefficient Algorithmic Complexity

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

n

The vulnerability exists due to quadratic time complexity in django.utils.http.parse_header_parameters() when parsing header values containing many separators inside a quoted parameter. A remote attacker can send a specially crafted request containing such values in Accept or Content-Type headers to cause a denial of service.

n

Unauthenticated requests can reach the parser through content negotiation performed by HttpRequest.accepts(). The per-call length limit does not bound the combined size of repeated headers.


3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-87890)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to induce server-side network requests.

n

The vulnerability exists due to acceptance of raster byte values without explicit GDALRaster wrapping in Django spatial lookups when preparing lookups from attacker-controlled bytes. A remote attacker can supply a VRT document referencing an external raster source to induce server-side network requests.

n

Exploitation requires an application to pass attacker-controlled bytes directly to a spatial lookup. GDAL opens these values through its in-memory virtual filesystem, and the resulting requests run as the Django process user.


4) Incorrect authorization (CVE-ID: CVE-2026-87975)

CWE-ID: CWE-863 - Incorrect Authorization

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to delete instances outside the limiting queryset or create instances through edit-only formsets.

n

The vulnerability exists due to improper authorization enforcement in Django model formsets when processing submitted data for models whose primary keys can be set through the form. A remote attacker can submit forged POST data to delete instances outside the limiting queryset or create instances through edit-only formsets.

n

Affected configurations include a OneToOneField or parent link used as the primary key of an inline formset's model, or a natural or UUID primary key included in the form's fields. Models using the default BigAutoField primary key are not affected.
