|

<!-- name=permission-model -->
|
||||
|
||||
The Node.js Permission Model is a mechanism for restricting access to specific
|
||||
resources during execution.
|
||||
The API exists behind a flag [`--experimental-permission`][] which when enabled,
|
||||
will restrict access to all available permissions.
|
||||
|
||||
The available permissions are documented by the [`--experimental-permission`][]
|
||||
flag.
|
||||
|
||||
When starting Node.js with `--experimental-permission`,
|
||||
the ability to access the file system, spawn processes, and
|
||||
use `node:worker_threads` will be restricted.
|
||||
|
||||
```console
|
||||
$ node --experimental-permission index.js
|
||||
node:internal/modules/cjs/loader:171
|
||||
const result = internalModuleStat(filename);

||||

|
||||
```
|
||||
|
||||
Allowing access to spawning a process and creating worker threads can be done
|
||||
using the [`--allow-child-process`][] and [`--allow-worker`][] respectively.
|
||||
|
||||
#### Runtime API
|
||||
|
||||
When enabling the Permission Model through the [`--experimental-permission`][]
|
||||
flag a new property `permission` is added to the `process` object.
|
||||
This property contains two functions:
|
||||
|

#### File System Permissions
|
||||
|
||||
To allow access to the file system, use the [`--allow-fs-read`][] and
|
||||
[`--allow-fs-write`][] flags:
|
||||
|
||||
```console
|
||||
$ node --experimental-permission --allow-fs-read=* --allow-fs-write=* index.js
|
||||
Hello world!
|
||||
(node:19836) ExperimentalWarning: Permission is an experimental feature
|
||||
(Use `node --trace-warnings ...` to show where the warning was created)
|
||||
```
|
||||
|
||||
The valid arguments for both flags are:
|
||||
|
||||
* `*` - To allow the all operations to given scope (read/write).
|
||||
* Paths delimited by comma (,) to manage reading/writing operations.
|
||||
|
||||
Example:
|
||||
|
||||
* `--allow-fs-read=*` - It will allow all `FileSystemRead` operations.
|
||||
* `--allow-fs-write=*` - It will allow all `FileSystemWrite` operations.
|
||||
* `--allow-fs-write=/tmp/` - It will allow `FileSystemWrite` access to the `/tmp/`
|
||||
folder.
|
||||
* `--allow-fs-read=/tmp/,/home/.gitignore` - It allows `FileSystemRead` access
|
||||
to the `/tmp/` folder **and** the `/home/.gitignore` path.
|
||||
|
||||
Wildcards are supported too:
|
||||
|
||||
* `--allow-fs-read:/home/test*` will allow read access to everything
|
||||
that matches the wildcard. e.g: `/home/test/file1` or `/home/test2`
|
||||
|
||||
There are constraints you need to know before using this system:
|
||||
|
||||
* Native modules are restricted by default when using the Permission Model.
|
||||
* Relative paths are not supported through the CLI (`--allow-fs-*`).
|
||||
The runtime API supports relative paths.
|
||||
* The model does not inherit to a child node process.
|
||||
* The model does not inherit to a worker thread.
|
||||
* When creating symlinks the target (first argument) should have read and
|
||||
write access.
|
||||
* Permission changes are not retroactively applied to existing resources.
|
||||
Consider the following snippet:
|
||||
```js
|
||||
const fs = require('node:fs');
|
||||
|
||||
// Open a fd
|
||||
const fd = fs.openSync('./README.md', 'r');
|
||||
// Then, deny access to all fs.read operations
|
||||
process.permission.deny('fs.read');
|
||||
// This call will NOT fail and the file will be read
|
||||
const data = fs.readFileSync(fd);
|
||||
```
|
||||
|
||||
Therefore, when possible, apply the permissions rules before any statement:
|
||||
|
||||
```js
|
||||
process.permission.deny('fs.read');
|
||||
const fd = fs.openSync('./README.md', 'r');
|
||||
// Error: Access to this API has been restricted
|
||||
```

This API is available through the [`--experimental-permission`][] flag.
|

`process.permission` is an object whose methods are used to manage permissions

Deny permissions at runtime.
|

|

The available scopes are:

|

* `fs.read` - File System read operations
|
||||
* `fs.write` - File System write operations
|

|

The reference has a meaning based on the provided scope. For example,
|
||||
the reference when the scope is File System means files and folders.
|
||||
|
||||
```js
|
||||
// Deny READ operations to the ./README.md file
|

process.permission.deny('fs.read', ['./README.md']);
|

// Deny ALL WRITE operations
|

If no reference is provided, a global scope is assumed, for instance,

`process.permission.has('fs.read')` will check if the process has ALL
|
||||
file system read permissions.
|
||||
|

The reference has a meaning based on the provided scope. For example,
