## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.2.388
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The worker forwards existing provider access credentials to a product service while local logins are enabled by default, creating a real credential-exposure risk. The feature is disclosed and configurable, and the inspected source does not establish misuse or a specific receiving host, so this supports a warning rather than a publish block.

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 worker's default-on local-login feature reads existing provider credentials and submits them to the product's local-subscription service. This creates a conditional credential-exposure risk; the inspected source does not establish how the receiving service uses the credentials.

- **Trigger:** Starting a Reason worker while local logins retain their default enabled setting.

- **Impact:** Provider access credentials leave the computer and reach the configured service without an affirmative forwarding choice shown in the inspected path.

- **Evidence paths:** .lpm-inspection-TUONDn/0-7c6b80b44275.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T08:58:27.691Z

### AI review details

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

- **Mechanism:** The worker reads local provider authentication files, extracts access credentials, and submits them to the local-subscription route through its configured API origin.

- **Rationale:** The worker forwards existing provider access credentials to a product service while local logins are enabled by default, creating a real credential-exposure risk. The feature is disclosed and configurable, and the inspected source does not establish misuse or a specific receiving host, so this supports a warning rather than a publish block.

- **Files touched:** .credentials.json, auth.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The manifest identifies a Windows x64 CLI binary package and declares no lifecycle scripts; the flagged sandbox location contains \`.mcp.json\` in a path-name array, not a configuration write., The CLI describes local provider logins as a feature and says it is enabled by default., The worker configuration defaults local logins to enabled., When the worker starts with local logins enabled, it invokes a helper that reads credentials and submits them through the local-subscription client., The helper reads provider authentication files; the inspected extraction code includes existing access-token fields., The client sends a request to its dedicated local-subscription route using the worker's configured API origin.

- **Evidence against:** The CLI describes the local-login feature and provides a way to disable it; the inspected code does not establish misuse of the submitted credentials., The sandbox-runtime scanner hit is a path-list entry and does not show an agent configuration mutation.

## Affected versions and remediation
