Summary
toui allows user-specific variables to be shared between users
Details

Impact

Websites that use Website.user_vars property in versions.

Patches

It affects versions v2.0.1 to v2.4.0. Please upgrade to v2.4.1

Workarounds

Do not use Website.user_vars in websites when using versions v2.0.1 to v2.4.0. Also, do not use Website.signin_user() in version v2.4.0 only.

Explanation

ToUI is using Flask-Caching (SimpleCache) to store user variables. My misunderstanding was that these caches are stored in the client's browser, but it seems that these are stored in the server side.
