Flask
2.0.1
One-liner (summary)
Description
Flask
Flask is a lightweight WSGI web application framework. It is designed to make getting started quick and easy, with the ability to scale up to complex applications. It began as a simple wrapper around Werkzeug and Jinja and has become one of the most popular Python web application frameworks.
Flask offers suggestions, but doesn't enforce any dependencies or project layout. It is up to the developer to choose the tools and libraries they want to use. There are many extensions provided by the community that make adding new functionality easy.
A Simple Example
# save this as app.py from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello, World!"
$ flask run * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

CVE-2023-30861: flask: Possible disclosure of permanent session cookie due to missing Vary: Cookie headerFlask 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` header when the session is accessed or modified, not when it is refreshed (re-sent to update the expiration) without being accessed or modified. This issue has been fixed in versions 2.3.2 and 2.2.5.Package Name: Flask Installed Version: 2.0.1 Fixed Version: 2.3.2, 2.2.5 References: access.redhat.com github.com github.com github.com github.com github.com github.com github.com github.com github.com linux.oracle.com linux.oracle.com lists.debian.org nvd.nist.gov security.netapp.com security.netapp.com ubuntu.com www.cve.org www.debian.org |
