An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `UpdateCacheMiddleware` and the `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated cookies, which allows remote attackers to read private data from the shared cache. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Chris Whyland for reporting this issue.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-fbb9501b22 advisory.

    Update `python-django5` to version 5.2.16

    Fixes three low-severity CVEs

    - CVE-2026-48588: Potential exposure of private data via cached Set-Cookie response
    - CVE-2026-53877: Heap buffer over-read in GDALRaster
    - CVE-2026-53878: Header injection possibility since DomainNameValidator accepted newlines in input


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

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

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

  - An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `UpdateCacheMiddleware` and the
    `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated
    cookies, which allows remote attackers to read private data from the shared cache. Earlier, unsupported
    Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would
    like to thank Chris Whyland for reporting this issue. (CVE-2026-48588)

  - An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16.
    `django.contrib.gis.gdal.GDALRaster` over-reads its in-memory buffer when constructed from a bytes object,
    which can disclose adjacent memory or cause service degradation via a potential segmentation fault when
    the `vsi_buffer` property is accessed. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and
    3.2.x) were not evaluated and may also be affected. Django would like to thank Bence Nagy for reporting
    this issue. (CVE-2026-53877)

  - An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `DomainNameValidator` does not
    prohibit newlines in domain names (unless used via a form field, since `CharField` strips newlines). If an
    application uses values with newlines in an HTTP response, header injection can occur. Django itself is
    unaffected because `HttpResponse` prohibits newlines in HTTP headers. Earlier, unsupported Django series
    (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank
    Bence Nagy for reporting this issue. (CVE-2026-53878)

The detected version of the Django Python package is 5.2.x prior to 5.2.16 or 6.0.x prior to 6.0.7. It is, therefore, affected by multiple vulnerabilities:

  - django.contrib.gis.gdal.GDALRaster over-reads its in-memory buffer when constructed from a bytes object,     which can disclose adjacent memory or cause service degradation via a potential segmentation fault when the     vsi_buffer property is accessed. (CVE-2026-53877)

  - DomainNameValidator does not prohibit newlines in domain names. If an application uses values with newlines     in an HTTP response, header injection can occur. (CVE-2026-53878)

  - UpdateCacheMiddleware and the cache_page() decorator cache responses that vary on cookies when the incoming     request carries unrelated cookies, which allows remote attackers to read private data from the shared cache.
    (CVE-2026-48588)

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

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

  - An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `UpdateCacheMiddleware` and the     `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated     cookies, which allows remote attackers to read private data from the shared cache. Earlier, unsupported     Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would     like to thank Chris Whyland for reporting this issue. (CVE-2026-48588)

Note that Nessus relies on the presence of the package as reported by the vendor.
