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: 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…

# Patch Next advisory brief: CVE-2025-53624

Advisory: docusaurus-plugin-content-gists vulnerability exposes GitHub Personal Access Token
IDs: CVE-2025-53624, GHSA-qf34-qpr4-5pph
Record: https://patchnext.com/advisories/cve-2025-53624 (revision 2, source checked 26 Oct 2026, 12:37 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 10.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: docusaurus-plugin-content-gists 4.0.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm docusaurus-plugin-content-gists: affected < 4.0.0; fixed in 4.0.0

## Suggested inspection (read-only)
- `npm ls docusaurus-plugin-content-gists --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on docusaurus-plugin-content-gists.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
