CVE-2026-48588
LowCVSS 3.1Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
A vulnerability was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `UpdateCacheMiddleware` and the `cache_page()` decorator cache responses that vary on cookies even when the incoming request carries unrelated cookies, allowing remote attackers to read private data from the shared cache.
Risk Assessment
The organization is at risk of leaking sensitive user data (e.g., sessions, preferences) stored in cookies, which could be read by unauthorized attackers from the shared cache.
Recommendation
Immediately upgrade Django to version 6.0.7 or 5.2.16 (or later). If an upgrade is not possible, temporarily disable caching of cookie-dependent responses or implement a custom caching layer.
Other vulnerabilities in Django
See all- CVE-2016-9014High
Django versions before 1.8.16, 1.9.11, and 1.10.3, when DEBUG is enabled, allow remote attackers to conduct DNS rebinding attacks due to failure to validate the HTTP Host header against ALLOWED_HOSTS.
- CVE-2016-7401High
The cookie parsing code in Django before 1.8.15 and 1.9.x before 1.9.10, when used on a site with Google Analytics, allows remote attackers to bypass an intended CSRF protection mechanism by setting arbitrary cookies.
- CVE-2016-2512High
The utils.http.is_safe_url function in Django before 1.8.10 and 1.9.x before 1.9.3 allows remote attackers to redirect users to arbitrary web sites. This can lead to phishing attacks or potentially cross-site scripting (XSS) attacks via a URL containing basic authentication.
- CVE-2015-5143High
Django versions before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 are vulnerable to denial of service attacks. Attackers can exploit unique session keys to consume session store resources.
- CVE-2014-0474High
In Django versions before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2, the FilePathField, GenericIPAddressField, and IPAddressField model field classes do not properly perform type conversion. This may allow remote attackers to have unspecified impact related to 'MySQL typecasting.'
- CVE-2026-5766Medium
An issue was discovered in versions 6.0 before 6.0.5 and 5.2 before 5.2.14 related to ASGI requests that can bypass the `FILE_UPLOAD_MAX_MEMORY_SIZE` limit when the `Content-Length` header is missing or understated. This may lead to large files being loaded into memory, causing service degradation.
- CVE-2026-35192Low
An issue was discovered in versions 6.0 before 6.0.5 and 5.2 before 5.2.14 regarding response headers that do not vary on cookies if a session is not modified, while `SESSION_SAVE_EVERY_REQUEST` is set to `True`. A remote attacker can steal a user's session after that user visits a cached public page.
- CVE-2026-1207Medium
In Django 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28, a vulnerability was found in raster lookups on RasterField (PostGIS only). Remote attackers can inject SQL via the band index parameter.
- CVE-2016-9013Critical
Django versions 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3 use a hardcoded password for a temporary database user, making it easier for remote attackers to gain access to the database server.
- CVE-2026-15920Medium
An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. django.contrib.admin.utils.display_for_field() renders URLField values as clickable links in the admin without validating the URL. A value stored with an unsafe scheme is displayed as a link on changelist and read-only admin pages, which allows cross-site scripting against staff users who click the link. Exploitation requires the unsafe value to already be stored in the database. URLField validation through a ModelForm or the admin rejects unsafe schemes, so this affects applications that persist URLField data without running model validation, for example through direct queryset writes, deserialization, or bulk import of untrusted input.
Original NVD description (English source)
An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `UpdateCacheMiddleware` and the `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated cookies, which allows remote attackers to read private data from the shared cache. 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 Chris Whyland for reporting this issue.
