What is the probability of a chat hack on NodeJS and MongoDB?

Question

JavaScript

Essentially NodeJS is JavaScript running on the server and in the user's browser. Databases on MongoDB are stored in text files, and authorization is not required to populate them.
Actually the question is how vulnerable is a pure NodeJS solution with MongoDB databases? Are injections and substitutions possible?

Answer 1

Only icons on the server will give you a 100% guarantee ...
But seriously, everything here depends not on the technology, but on the programmer and the admin. There is no fundamental difference in Java Oracle, ASP MSSQL, PHP MYSQL, NODE MONGO.
