## 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:** 0.61.0
- **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.

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

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:** Connector launches allow all OpenCode tool permissions while the plugin can initiate turns from mesh messages. This is a concrete dangerous capability, but no malicious installation behavior was established.

- **Trigger:** Launching an OpenCode agent through the connector and receiving eligible mesh messages.

- **Impact:** Agent tool actions can proceed without interactive permission approval during these launches.

- **Evidence paths:** dist/index.js, dist/plugin/index.js, dist/serve.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-04T22:25:16.805Z

### AI review details

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

- **Mechanism:** The launch injects permission: allow into the process configuration, and the plugin submits automatic agent turns.

- **Rationale:** Source supports a warning for launch-time permission bypass combined with automatic mesh-driven agent turns. The scanner's malicious and reverse-shell labels are not supported by the inspected execution path.

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 89.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The connector launch sets OpenCode permissions to allow and loads its bundled plugin., The configuration is passed through OPENCODE\_CONFIG\_CONTENT to the local serve helper., The plugin automatically drives agent turns for eligible incoming mesh messages., The helper starts OpenCode on loopback with a freshly generated server password.

- **Evidence against:** package.json has no automatic installation lifecycle hooks or runtime self-dependency., The indicated agent configuration locations contain embedded documentation, not configuration writes., The flagged socket and process behavior implements local server startup and terminal attachment; no reverse shell was identified.

## Affected versions and remediation

This report applies to @cotal-ai/connector-opencode@0.61.0.

- Review the evidence and your use of @cotal-ai/connector-opencode@0.61.0 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.
