YITH-Chat is a big security risk

Just got a notification from Google regarding the YITH Chat plugin:

We’ve detected the following issue(s) with your security rules:

any user can read your entire database

any user can write to your entire database

Without strong security rules, anyone who has the address of your database can read/write to it, leaving your data vulnerable to attackers stealing, modifying or deleting data as well as creating costly operations.

I uninstalled this plugin immediately.
