An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. `django.utils.translation.check_for_language()` is subject to a potential denial-of-service attack when given many distinct, very long language codes, which are retained as keys in an in-memory cache and consume process memory. Such codes reach the function through the `django.views.i18n.set_language()` view, which is not routed by default. The consumed memory is bounded, since request data is limited by the `DATA_UPLOAD_MAX_MEMORY_SIZE` setting (default 2.5 MB) and the cache holds a fixed maximum number of entries. Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected. Django would like to thank Jaeyoung Jang for reporting this issue.

    Package        : python-django     Version        : 2:2.2.28-1~deb11u13 3:3.2.25-0+deb12u4     CVE ID         : CVE-2026-15337 CVE-2026-15920

    Two issues were discovered in Django, the Python-based web     development framework.

    CVE-2026-15337

        Avoid a potential denial-of-service vulnerability in the         check_for_language() method in the django.utils.translation         module.

        This method was subject to a potential denial-of-service (DoS)         attack when checking many distinct, very long language codes. To         mitigate this vulnerability, language codes longer than 500         characters are now rejected before the cached lookup.

    CVE-2026-15920

        Prevent a potential cross-site scripting (XSS) attack via         bogus URLField values in the Django admin.

        The admin renders URLField values as clickable links on         'changelist' views and read-only fields. This link was hitherto         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 the URLValidator class before a link is rendered         and displayed as plain text if validation fails.

    For Debian 11 bullseye, these problems have been fixed in version     2:2.2.28-1~deb11u13.

    For Debian 12 bookworm, these problems have been fixed in version     3:3.2.25-0+deb12u4.

    We recommend that you upgrade your python-django packages.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. GeoDjango spatial lookups
    optimistically parse the right-hand-side value as a raster by passing it to the
    `django.contrib.gis.gdal.GDALRaster` constructor. Any value used in a spatial lookup against a
    `GeometryField` or `RasterField` reaches this constructor, including untrusted input, for example a
    spatial-field filter submitted through the Django admin changelist query string by a staff user with view
    permission. A `dict`, or a `str` holding its JSON representation, is opened in write mode regardless of
    the constructor's `write=False` default, allowing a file with an attacker-chosen name and contents to be
    written through a file-backed GDAL driver. Any other `str` is treated as a datasource, allowing an
    outbound network request through a GDAL virtual filesystem handler. Writing a file to a location later
    imported by the application can result in remote code execution. Earlier, unsupported Django series (such
    as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected. Django would like to thank Bence
    Nagy, localhost-detect, and kimchunbok_ for reporting this issue. (CVE-2026-15307)

  - An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8.
    `django.utils.translation.check_for_language()` is subject to a potential denial-of-service attack when
    given many distinct, very long language codes, which are retained as keys in an in-memory cache and
    consume process memory. Such codes reach the function through the `django.views.i18n.set_language()` view,
    which is not routed by default. The consumed memory is bounded, since request data is limited by the
    `DATA_UPLOAD_MAX_MEMORY_SIZE` setting (default 2.5 MB) and the cache holds a fixed maximum number of
    entries. Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may
    also be affected. Django would like to thank Jaeyoung Jang for reporting this issue. (CVE-2026-15337)

  - An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. GeoDjango's
    `django.contrib.gis.geos.GEOSGeometry` is subject to a potential denial-of-service when parsing deeply
    nested `GEOMETRYCOLLECTION` objects supplied as well-known text (WKT), well-known binary (WKB), or hex-
    encoded WKB, which triggers unbounded recursion and a segmentation fault in the underlying GEOS library.
    Spatial field lookups and the `django.contrib.gis.forms.GeometryField` form field are also affected.
    Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be
    affected. Django would like to thank Andrew MacPherson and kimchunbok_ for reporting this issue.
    (CVE-2026-15830)

  - An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8.
    `django.contrib.admin.utils.display_for_field()` renders `URLField` values as clickable links in the admin
    without validating the URL. A value stored with an unsafe scheme is displayed as a link on changelist and
    read-only admin pages, which allows cross-site scripting against staff users who click the link.
    Exploitation requires the unsafe value to already be stored in the database. `URLField` validation through
    a `ModelForm` or the admin rejects unsafe schemes, so this affects applications that persist `URLField`
    data without running model validation, for example through direct queryset writes, deserialization, or
    bulk import of untrusted input. Django would like to thank Egor Saltykov for reporting this issue.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21543-1 advisory.

    Changes in python-Django:

    - CVE-2026-15307: server-side file-write and request forgery via spatial lookups (bsc#1272997)
    - CVE-2026-15337: potential denial-of-service vulnerability in `check_for_language()` (bsc#1272998)
    - CVE-2026-15830: potential denial-of-service vulnerability via nested geometry collections (bsc#1272999)
    - CVE-2026-15920: potential cross-site scripting via `URLField` values in the admin (bsc#1273000)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The detected version of the Django Python package is 5.2.x prior to 5.2.17 or 6.0.x prior to 6.0.8. It is, therefore, affected by multiple vulnerabilities, including:

  - GeoDjango spatial lookups pass untrusted input to the GDALRaster constructor, allowing an attacker to write     arbitrary files via a file-backed GDAL driver or trigger outbound network requests via GDAL virtual filesystem     handlers, potentially resulting in remote code execution. (CVE-2026-15307)

  - django.contrib.admin.utils.display_for_field() renders URLField values as clickable links without validating     the URL scheme, allowing cross-site scripting against staff users who click a link with an unsafe scheme stored     in the database. (CVE-2026-15920)

  - django.utils.translation.check_for_language() retains many distinct, very long language codes as keys in an     in-memory cache, allowing a potential denial-of-service attack that consumes process memory. (CVE-2026-15337)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3503-1 advisory.

    - CVE-2026-15307: server-side file-write and request forgery via spatial lookups (bsc#1272997).
    - CVE-2026-15337: potential denial-of-service vulnerability in `check_for_language()` (bsc#1272998).
    - CVE-2026-15830: potential denial-of-service vulnerability via nested geometry collections (bsc#1272999).
    - CVE-2026-15920: potential cross-site scripting via `URLField` values in the admin (bsc#1273000).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
