How to fix?

There is no fixed version for Echo:latest python-django.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-django package and not the python-django package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
