NewCVE-2026-113593 (opens in a new tab)How to fix?
Upgrade Django to version 5.2.19, 6.0.10, 6.1.3 or higher.
Overview
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Affected versions of this package are vulnerable to Use of Cache Containing Sensitive Information in the _generate_cache_key function in django/utils/cache.py. An attacker can receive another user's cached response by sending a request that omits a header named in the response Vary header, because an absent header and a header present with an empty value are assigned the same cache key. This affects applications using UpdateCacheMiddleware or cache_page() whose cached responses vary on a request header.
