If I don't see asterisks, I'm not hitting save on the field with a secret in it. Maybe they were setting them programmatically? They should definitely still be looking to pass some kind of a secret flag, though. This is a weird problem for a company like Vercel to have.
Vercel April 2026 security incident
We'll keep dangerous devices like the SuperBox in our homes, if it helps us get access to free movies and tv.
We'll use single-use plastics, even if we know they're bad for the environment, because they're just so damn easy.
We'll let AI run that thing for us, because it's just too easy.
A whole generation has grown up without knowing what it was like to infect your computer with AIDS trying to download an MP3, and it shows. That caution will come back, just at a terrible cost.
More generically, our species' Achilles heel is our inability to factor in the long-term cost of negative externalities when evaluating processes that yield short-term positive results.
If you spin up an EC2 instance with an ftp server and check the "Encrypt my EBS volume" checkbox, all those files are 'encrypted at rest', but if your ftp password is 'admin/admin', your files will be exposed in plaintext quite quickly.
Vercel's backend is of course able to decrypt them too (or else it couldn't run your app for you), and so the attacker was able to view them, and presumably some other control on the backend made it so the sensitive ones can end up in your app, but can't be seen in whatever employee-only interface the attacker was viewing.
For non-sensitive environment variables, they also show you the value in the dashboard so you can check and edit them later.
Things like 'NODE_ENV=production' vs 'NODE_ENV=development' is probably something the user wants to see, so that's another argument for letting the backend decrypt and display those values even ignoring the "running your app" part.
You're welcome to add an input that goes straight to '/dev/null' if you want, but it's not exactly a useful feature.
What's best practice to handle env vars? How do poeple handle them "securely" without it just being security theater? What tools and workflows are people using?
However I do feel now like my sensitive things are better off deployed on a VPS where someone would need a ssh exploit to come at me.
Notice how their tutorial says "run 'dotenvx run -- yourapp'". If you did 'dotenvx run -- env', all your secrets would be printed right there in plaintext, at runtime, since they're just encrypted at rest.
The equivalent in vercel would be encrypted in the database (the encrypted '.env' file), with a decryption key in the backend (the '.env.keys' file by default in dotenvx) used to show them in the frontend and decrypt them for running apps.
Various certifications require this, I guess because they were written before hyper scalers and the assumed attack vector was that someone would literally steal a hard drive.
A running machine is not “at rest”, just like you can read files on your encrypted Mac HDD, the running program has decrypted access to the hard drive.
So sensitive doesn’t mean encrypted. It means the UI doesn’t show the dev what value’s stored there after they’ve updated it. Not sensitive means it’s still visible. And again, I presume this is only a UI thing, and both kinds are stored encrypted in the backend.
I don’t work for Vercel, but I’ve use them a bit. I’m sure there are valid reasons to dislike them, but this specific bit looks like a strawman.
Initially, we identified a limited subset of customers whose Vercel credentials were compromised. We reached out to that subset and recommended that they rotate their credentials immediately.
At this time, we do not have reason to believe that your Vercel credentials or personal data have been compromised.

And I thought it was bad when my son got compromised by a Roblox cheat, but they only they grabbed his Gamepass cookies and bought 4 Minecraft licenses, which MS quickly refunded...
