    "value" : "To mitigate this issue, disable the `django.middleware.cache.UpdateCacheMiddleware` in your Django application's `settings.py` file by removing it from the `MIDDLEWARE` list. This action prevents the erroneous caching of requests with an asterisk in the `Vary` header, thereby eliminating the information disclosure vulnerability. Be aware that disabling this middleware will also deactivate Django's built-in caching functionality, which may affect application performance and behavior. A restart of the Django application server is required for this change to take effect.",
