"The detected version of the Django Python package is 5.2.x prior to 5.2.18, or 6.0.x prior to 6.0.9, or 6.1.x prior
to 6.1.2. It is, therefore, affected by multiple vulnerabilities, including:

  - 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. (CVE-2026-77050)

  - 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. (CVE-2026-84429)

  - 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. (CVE-2026-87890)

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