NVD Description

Note: Versions mentioned in the description apply only to the upstream py3.13-django-bin package and not the py3.13-django-bin package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
