"The detected version of the Django Python package is 5.2.x prior to 5.2.15 or 6.0.x prior to 6.0.6. It is,
therefore, affected by multiple vulnerabilities, including:

  - django.middleware.cache.UpdateCacheMiddleware does not add Authorization to the Vary response header for
    requests bearing that header without Cache-Control: public, which allows remote attackers to read private
    cached responses via unauthenticated requests to the same URL. (CVE-2026-35193)

  - django.utils.cache.has_vary_header() does not strip leading or trailing whitespace from Vary response
    header values before comparison, which allows remote attackers to read cached responses via requests to
    URLs whose responses contain whitespace-padded Vary header values. (CVE-2026-48587)

  - django.core.mail.backends.smtp.EmailBackend fails to prevent reuse of a partially-initialized connection
    after a failed STARTTLS handshake when fail_silently=True, which allows on-path network attackers to read
    email content via cleartext interception. (CVE-2026-7666)

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