Alpine: multiple py3-django packages: security update to 5.2.15-r0

low Tenable Cloud Security Plugin ID 443094

Description

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

- An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15.
`django.http.HttpRequest.get_signed_cookie` in Django uses a non-injective salt derivation (concatenating
the cookie name and salt argument), which allows a remote attacker to use a cookie in a context different
from the one where it was signed, via distinct `(name, salt)` pairs that produce the same concatenation.
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 Peng Zhou for reporting this issue. (CVE-2026-6873)

- An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15.
`django.core.mail.backends.smtp.EmailBackend` in Django 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. 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 Kasper
Dupont for reporting this issue. (CVE-2026-7666)

- An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6.
`django.middleware.cache.UpdateCacheMiddleware` in Django does not match `Cache-Control` response
directives case-insensitively, which allows remote attackers to read responses that were incorrectly
cached because their `Cache-Control` directives used uppercase or mixed-case values. 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 Ahmed Badawe for reporting this issue. (CVE-2026-8404)

- An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6.
`django.middleware.cache.UpdateCacheMiddleware` in Django 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. 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 Shai Berger for reporting this issue. (CVE-2026-35193)

- An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6.
`django.utils.cache.has_vary_header()` in Django 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. 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 Navid Rezazadeh for reporting this issue. (CVE-2026-48587)
