## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.135.21
- **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 connector's startup path mirrors credentials from several unrelated AI clients into its private Jcode home, expanding the agent's access without a visible consent check. I found no package-source evidence that those credentials are transmitted to an unrelated host, so this warrants a warning rather than a block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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:** Default host startup stages credentials from several unrelated AI clients in the private Jcode runtime, creating unrequested access for the agent.

- **Trigger:** When the Cotal core launches a Jcode connector host seat.

- **Impact:** The Jcode runtime can access credentials for other AI services and may use them to act through those services. The package source does not establish an unrelated-host transmission.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T10:07:54.806Z

### AI review details

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

- **Mechanism:** The host inventories credential files under the user's home directory and copies them into the seat's private Jcode home before starting Jcode; no opt-in guard is visible on this path.

- **Rationale:** The connector's startup path mirrors credentials from several unrelated AI clients into its private Jcode home, expanding the agent's access without a visible consent check. I found no package-source evidence that those credentials are transmitted to an unrelated host, so this warrants a warning rather than a block.

- **Files touched:** .claude/.credentials.json, .codex/auth.json, .gemini/oauth\_creds.json, .cursor/auth.json, .config/github-copilot/hosts.json, .config/github-copilot/apps.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** Starting a Jcode host seat calls mirrorJcodeCredentials before launching the private Jcode instance., The mirrored credential inventory includes files for Claude, Codex, Gemini, Cursor and GitHub Copilot., The mirror copies inventoried credentials into the private Jcode home; the source does not show this package transmitting them to a foreign host., The manifest exports a connector module and has no install lifecycle script.

- **Evidence against:** The package is a Jcode connector, and the credential mirroring occurs as part of its host startup flow., The reviewed package source does not establish that the mirrored credentials are sent to an unrelated host.

## Affected versions and remediation
