QUESTION
I have hosted my MERN app on Heroku , but whenever I implement helmet in app.js file it's causing this issue.
...ANSWER
Answered 2021-Jan-26 at 01:15Helmet maintainer here.
This is happening because of something called Content Security Policy, which Helmet sets by default. To solve your problem, you will need to configure Helmet's CSP.
MDN has a good documentation about CSP which I would recommend reading for background. After that, take a look at Helmet's README to see how to configure its CSP component.
To give some help specific to this question: this error is telling you that the script-src
directive of your CSP does not allow inline JavaScript, and so it was blocked.
This is considered "inline" JavaScript:
QUESTION
Learning the basics of MongoDB, I read that MongoDB is vulnerable to injection attacks out-of-the-box. In node, this can be prevented using the help of the module mongo-sanitize. So far, so good. Now let's add Mongoose to the equation.
If we are using Mongoose
- Do we still need to sanitize MongoDB inputs? Should we still use mongo-sanitize along with Mongoose?
- Does Mongoose offer any explicit injection protection at all, or does the protection come from enforcing types in schemas and models?
I remember reading that Mongoose can prevent injections to some extent, but I don't know the specifics, or if it is redundant to sanitize against Mongoose.
...ANSWER
Answered 2020-Sep-11 at 00:19Like the article mentioned the problem arises when the users doesn't send a string like
'bergur' and 'myawesomepassword' but instead sends {"$ne": null}
for usernames and passwords.
If you create a schema and define username and password as strings, then Mongoose will convert it to string and you avoid the problem.
Regarding the where injection, mongo-sanitize wouldn't help you there. The solution is simply not to ever use the $where operator
So to simply answer your question:
- No you don't need to use mongo-sanitize
- No explicit injection protection, the protection comes from schemas and models.

QUESTION
Im working on my first node application. Now it is ready to deploy and I want secure my application. So I used these libraries to secure it.
...ANSWER
Answered 2019-Dec-09 at 05:48You can't just pile on some "security" library and magically become "secure". Don't you think that if this were possible, all of these packages would be applied automatically, already?
Let's look at what these modules actually do...
express-mongo-sanitizeThis module searches for any keys in objects that begin with a $ sign or contain a ., from req.body, req.query or req.params. It can then either:
- completely remove these keys and associated data from the object, or
- replace the prohibited characters with another allowed character.
This is (arguably) a really bad idea. If you were escaping things correctly for use in your queries in the first place, such a sanitizing function wouldn't need to exist. And then, you wouldn't have to worry about a module like this totally wrecking your data structure. Furthermore, if you did rely on this sort of library, you can be sure that there will be some way around it, as it isn't solving the fundamental problem... that mixing the contexts of data and commands is dangerous and error-prone.
helmetHelmet is a collection of 14 smaller middleware functions that set HTTP response headers.
This package has a whole bunch of stuff, from HSTS to disabling caching. None of them are some sort of security silver bullet, as the author of this package cautions at the very top of the readme file:
It's not a silver bullet, but it can help!
You should understand what all these headers actually do so you can use the right ones. Additionally, much of this you'll want to apply at your web server (such as Nginx) rather than dealing with it in your application.
xss-cleanThis will sanitize any data in req.body, req.query, and req.params. You can also access the API directly if you don't want to use as middleware.
Nothing says "security" like an NPM package with near-zero documentation that hasn't been touched in 4 years. It's really an awful idea to begin with though. You should be escaping data for the context of HTML only when you insert that data into HTML. If you do it early, you're just corrupting your data. Misunderstanding of this can actually lead you to future security problems, not to mention a mess of a broken application. (See also: The holy grail of cleaning input and output in php?)
hppExpress middleware to protect against HTTP Parameter Pollution attacks
This module takes multiple query string variables and prevents them from coming back as an array. This is fine if that's what you want, but having multiple of the same key in the query string is intended, and well-documented behavior that your application can use. If this is a problem, you should actually fix your application rather than relying on this module to break the standard behavior.
corsAs @jfriend00 points out, the CORS library helps you add the appropriate response headers to enable cross-origin access to data. This can be secure and appropriate, but not something you probably want to enable by default.
express-rate-limitBasic rate-limiting middleware for Express. Use to limit repeated requests to public APIs and/or endpoints such as password reset.
This can be useful, if you want rate limiting. I'd suggest doing this though at the web server level rather than messing with it in your application. There are efficient and fast modules/configurations for Nginx and similar, which are going to be able to handle this better than building it into every Node.js application you build.
TL;DR;Understand what it is that you're protecting against, or you're absolutely doomed to be insecure no matter what modules you install. Security isn't some patch you install.

Answered 2018-Oct-15 at 16:33While you could use $eq
to ensure an equality comparison is used in the query, your express route handler is a better place to perform request format validation.
A valid POST /login
should have userName
and password
string fields in the body of the request. If not, it should be rejected before it even gets to Mongoose.
