CVE-2018-14574: Open redirect possibility inCommonMiddleware
If thedjango.middleware.common.CommonMiddlewareand theAPPEND_SLASHsetting are both enabled, and if the project has a URL pattern that accepts any path ending in a slash (many content management systems have such a pattern), then a request to a maliciously crafted URL of that site could lead to a redirect to another site, enabling phishing and other attacks.
