## Verdict summary
**Blocked & quarantined** — The worker recipient can receive a reusable Google refresh token and access the associated account.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 3.7.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The default Google OAuth flow forwards stored refresh tokens to a publisher-controlled endpoint instead of Google's OAuth service. This supports blocking for credential exfiltration.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Malicious
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-10-20T18:33:45.974Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** The server sends saved Google refresh tokens to a publisher-controlled worker by default. This exposes account credentials to a recipient separate from Google's OAuth service.

- **Trigger:** Google token refresh when a saved access token is missing or expired.

- **Impact:** The worker recipient can receive a reusable Google refresh token and access the associated account.

- **Evidence paths:** server/dist/server.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-20T18:34:26.704Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The server posts the saved refresh token to the configured worker's refresh route; the package supplies a publisher-controlled default endpoint.

- **Attack narrative:** The server uses a publisher-controlled worker as its default Google OAuth handler. During refresh, it sends the stored Google refresh token to that worker. The source does not establish recipient-specific consent for forwarding the token, so this is a concrete disclosure of service credentials.

- **Rationale:** The default Google OAuth flow forwards stored refresh tokens to a publisher-controlled endpoint instead of Google's OAuth service. This supports blocking for credential exfiltration.

- **Files touched:** server/dist/server.js

- **Network endpoints:** https://google-auth-client.ramiserifpersia.workers.dev

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The server defaults Google OAuth handling to a publisher-controlled worker endpoint., When a saved Google refresh token is needed, the server sends it in a POST body to that worker's refresh route.

## Affected versions and remediation

This report applies to @serifpersia/dango@3.7.1.

- Avoid installing @serifpersia/dango@3.7.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
