GitHub Security Advisory

docusaurus-plugin-content-gists vulnerability exposes GitHub Personal Access Token

✓ GitHub Reviewed CRITICAL Has CVE

Advisory Details

## GitHub Personal Access Token Exposure in docusaurus-plugin-content-gists

### Summary

docusaurus-plugin-content-gists versions prior to 4.0.0 are vulnerable to exposing GitHub Personal Access Tokens in production build artifacts when passed through plugin configuration options. The token, intended for build-time API access only, is inadvertently included in client-side JavaScript bundles, making it accessible to anyone who can view the website's source code.

### Affected Versions

- All versions < 4.0.0

### Patched Versions

- Version 4.0.0 and later

### Impact

When using the affected versions with the recommended configuration pattern:

```javascript
plugins: [
[
'docusaurus-plugin-content-gists',
{
personalAccessToken: process.env.GITHUB_PERSONAL_ACCESS_TOKEN,
},
],
]
```

The GitHub Personal Access Token is included in the webpack bundle and exposed in production builds at:
- `/build/assets/js/main.[hash].js`

This allows malicious actors to:
- Extract the GitHub Personal Access Token from the website's JavaScript files
- Use the stolen token to access the token owner's GitHub account with the granted permissions
- Potentially access private gists, repositories, or perform other actions depending on the token's scope

## Mitigation steps

1. Immediately revoke access to the GitHub PAT that was used: https://github.com/settings/tokens

### Migration steps

1. Update to version 4.0.0+: `npm install docusaurus-plugin-content-gists@^4.0.0`
3. Remove `personalAccessToken` from your plugin configuration
4. Ensure `GH_PERSONAL_ACCESS_TOKEN` is set in your build environment

Affected Packages

npm docusaurus-plugin-content-gists
Affected versions: 0 (fixed in 4.0.0)
