Descripción

*** Pendiente de traducción *** An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6.<br /> `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.<br /> Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.<br /> Django would like to thank Navid Rezazadeh for reporting this issue.
