CVE-2026-113593
Last modified
CVE-2026-113593 is a low-severity vulnerability rated 3.1/10 on the CVSS scale. An issue was discovered in Django 6.1 before 6.1.3, 6.0 before 6.0.10, and 5.2 before 5.2.19. The `django.middleware.cache.UpdateCacheMiddleware` and the `django.views.decorators.cache.cache_page()` decorator generate identical cache keys for requests that omit a header listed in the response’s `Vary` header and requests that include that header with an empty value, potentially allowing remote attackers to access private data cached for another request. Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected. Django would like to thank Andrew Gonzalez for reporting this issue..
