# `@endo/lockdown`

We often need to upgrade a JavaScript environment to HardenedJS as a side
effect of importing a module, so that later modules can rely on the hardened
environment.
The `@endo/lockdown` package simply ensures that SES has both initialized
and locked down the environment.

```js
import '@endo/lockdown'
import 'hardened-modules...';
```

The HardenedJS environment is a subset of the Endo environment.
Use [`@endo/init`](../init) for a more comprehensive upgrade.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
