- Impact Websites that use Website.uservars 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.uservars in websites when using versions v2.0.1 to v2.4.0. Also, do not use Website.signinuser() 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.
Recommended action: Upgrade to 2.4.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
