## 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:** 0.60.0
- **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:** An explicit connector launch supplies an OpenCode configuration allowing all permissions. This is a concrete agent capability risk, but no confirmed malicious attack was established.

- **Trigger:** Launching an OpenCode session through the connector's buildLaunch operation.

- **Impact:** The launched agent can perform tool operations without normal permission prompts.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-04T09:30:57.678Z

### AI review details

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

- **Mechanism:** The connector places its permission and plugin configuration in OPENCODE\_CONFIG\_CONTENT, which the helper inherits when starting OpenCode.

- **Rationale:** Source inspection supports a warning for explicit launch-time agent permission configuration, not the scanner's malicious classification. No concrete block-eligible attack was established.

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json has no automatic installation lifecycle hooks., dist/index.js builds an OpenCode launch configuration that allows all permissions and loads the bundled plugin., The configuration is passed through OPENCODE\_CONFIG\_CONTENT to the launched helper., dist/serve.js starts OpenCode on loopback with a generated authentication password; its process wiring supports a local server and TUI., dist/plugin/index.js stays off the mesh when no managed-session identity is present.

- **Evidence against:** No concrete malicious installation, credential theft, or reverse-shell behavior was established., The indicated agent configuration locations contain embedded documentation rather than executable configuration writes.

## Affected versions and remediation

This report applies to @cotal-ai/connector-opencode@0.60.0.

- Review the evidence and your use of @cotal-ai/connector-opencode@0.60.0 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.
