This codemod sets the most secure parameters when Flask applications call
set_cookieon a response object. Without these parameters, your Flaskapplication cookies may be vulnerable to being intercepted and used to gain access to sensitive data.
The changes from this codemod look like this:
from flask import Flask, session, make_response app = Flask(__name__) @app.route('/') def index(): resp = make_response('Custom Cookie Set') - resp.set_cookie('custom_cookie', 'value') + resp.set_cookie('custom_cookie', 'value', secure=True, httponly=True, samesite='Lax') return respMore reading
