Flask is a lightweight WSGI web application framework. When all of the following conditions are met, a response containing data intended for one client may be cached and subsequently sent by the proxy to other clients. If the proxy also caches Set-Cookie headers, it may send one client's session cookie to other clients. The severity depends on the application's use of the session and the proxy's behavior regarding cookies. The risk depends on all these conditions being met. 1. The application must be hosted behind a caching proxy that does not strip cookies or ignore responses with cookies. 2. The application sets session.permanent = True 3. The application does not access or modify the session at any point during a request. 4. SESSION_REFRESH_EACH_REQUEST enabled (the default). 5. The application does not set a Cache-Control header to indicate that a page is private or should not be cached. This happens because vulnerable versions of Flask only set the Vary: Cookie head...
