"details" : "## GitHub Personal Access Token Exposure in docusaurus-plugin-content-gists\n\n### Summary\n\ndocusaurus-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.\n\n### Affected Versions\n\n- All versions < 4.0.0\n\n### Patched Versions\n\n- Version 4.0.0 and later\n\n### Impact\n\nWhen using the affected versions with the recommended configuration pattern:\n\n```javascript\nplugins: [\n [\n 'docusaurus-plugin-content-gists',\n {\n personalAccessToken: process.env.GITHUB_PERSONAL_ACCESS_TOKEN,\n },\n ],\n]\n```\n\nThe GitHub Personal Access Token is included in the webpack bundle and exposed in production builds at:\n- `/build/assets/js/main.[hash].js`\n\nThis allows malicious actors to:\n- Extract the GitHub Personal Access Token from the website's JavaScript files\n- Use the stolen token to access the token owner's GitHub account with the granted permissions\n- Potentially access private gists, repositories, or perform other actions depending on the token's scope\n\n## Mitigation steps\n\n 1. Immediately revoke access to the GitHub PAT that was used: https://github.com/settings/tokens\n\n### Migration steps\n\n 1. Update to version 4.0.0+: `npm install docusaurus-plugin-content-gists@^4.0.0`\n 3. Remove `personalAccessToken` from your plugin configuration\n 4. Ensure `GH_PERSONAL_ACCESS_TOKEN` is set in your build environment",
