Malicious libraries can steal all your application secrets in Elixir
I used E in the 90s: http://erights.org/
I haven't kept up with newer systems but I've heard of https://github.com/endojs/endo and just came across http://reports-archive.adm.cs.cmu.edu/anon/home/anon/isr2017... (which says "in the style of the E programming language" -- that's as far as I've read) while looking that up.
WebAssembly was designed to follow the same capability security principles. CHERI too as someone else just brought up.

Building an Extension System on the Web
There are other potential solutions I haven’t explored close enough (like Endo and SES), or completely omitted as they’re based on an imperfect blacklist-based approach to security (like sandboxed WebWorkers). However, the mentioned 4 solutions are the top contenders, at least in my mind.

Harvesting credit card numbers and passwords from your site
I don't know why you are being silently downvoted, as I think it is worth talking about the potential of using static analysis to improve things.
One promising approach is Endo[0] which "uses LavaMoat to automatically generate reviewable policies that determine what capabilities will be distributed to third party dependencies."

Deno 1.26
Yea you could restrict the app by whitelisting only the network services and folders that it will use and that's pretty valuable though at least on Linux could already easily be achieved otherwise. It's good that Deno makes it easy but let's be honest, most people will just pass -A.
I'd love to see a permissions system on a library basis. It would ask the first time a dependency is added and when a new permission is requested after an update. Javascript doesn't make that easy though by being so dynamic. SES could maybe help: https://github.com/endojs/endo/blob/master/packages/ses/READ...

Node runtime that sandboxes all NPM dependencies by default
I was poking around on the internet a bit earlier and I found this project. It looks pretty cool, and I figured perhaps a few of y'all might find it cool too!
I have no idea if it actually sandboxes networking by default. This other project, endo[0], seems to add some of that functionality.
Regardless of the maturity though, it makes me excited to see this type of work getting done now!
(What made me want to research it was this[1] thread from the other day.)

Open source maintainer pulls the plug on NPM packages colors and faker, now what
Fortunately the problem could become more tractable if something like SES / Endo takes off:
"Endo protects program integrity both in-process and in distributed systems. SES protects local integrity, defending an application against supply chain attacks: hacks that enter through upgrades to third-party dependencies. Endo does this by encouraging the Principle of Least Authority. ... Endo uses LavaMoat to automatically generate reviewable policies that determine what capabilities will be distributed to third party dependencies."
