## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 14 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.41.2
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

No confirmed malicious attack surface. The reviewed process and HTTP behavior is a local Opencode connector launched through its runtime API.

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:** No confirmed malicious attack surface. The reviewed process and HTTP behavior is a local Opencode connector launched through its runtime API.

- **Trigger:** A user or host explicitly launches the Opencode connector.

- **Impact:** Creates connector-specific local state and a temporary local service only.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-05T03:16:22.349Z

### AI review details

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

- **Mechanism:** Starts and attaches to a loopback Opencode service.

- **Rationale:** Static findings reflect the connector's intended local launcher behavior. There is no install-time execution, external endpoint, secret harvesting, remote code path, or persistence behavior that establishes malicious intent.

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason.

- **Evidence for AI clean decision:** The manifest exposes a dist entrypoint and has no install lifecycle hook., The launcher starts the configured local Opencode binary, binds it to loopback, and probes its local session endpoint., The connector explicitly returns the bundled serve shim as its user-invoked launch command.

- **Evidence against:** No preinstall, install, or postinstall script is present., The network target in the reviewed launcher is only 127.0.0.1; no external exfiltration endpoint was found., Process execution is limited to Opencode and local process inspection, with no shell-string execution or remote payload loading.

## Affected versions and remediation

This report applies to @cotal-ai/connector-opencode@0.41.2.

- Review the evidence and your use of @cotal-ai/connector-opencode@0.41.2 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
