Python Library Django 5.2.x < 5.2.15 / 6.0.x < 6.0.6 Multiple Vulnerabilities

low Nessus Plugin ID 318785

Language:

Synopsis

A Python library installed on the remote host is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to Django version 5.2.15, 6.0.6 or later.
