Echo: django: security update to 5.2.15

low Tenable Cloud Security Plugin ID 464838

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the django library and its related packages to version 5.2.15 or later.
