## 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:** 5.149.1
- **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 deliberate bypass and obfuscation make this a substantial runtime agent-capability risk. Lack of an install hook and no verified exfiltration path keep the evidence below the publication-block threshold.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 93.0%
- **Started:** 2026-09-14T11:54:38.455Z
- **Finished:** 2026-09-14T11:55:44.404Z
- **Download time:** 506 ms
- **Static scan time:** 8749 ms
- **AI review time:** 56690 ms
- **Total time:** 65949 ms

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:** At runtime, the optional Claude bridge suppresses Claude CLI permission checks and routes model-requested tool calls to an external orchestrator. It also disguises platform and tool identifiers before forwarding prompts.

- **Trigger:** Running the bot with the Claude bridge provider enabled.

- **Impact:** An attacker controlling prompts or model behavior could obtain unreviewed execution through the configured agent tool surface.

- **Evidence paths:** claude-bridge/src/claude.js, claude-bridge/src/tools.js, dist/services/edit-governor.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-14T11:55:44.404Z

### AI review details

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

- **Mechanism:** Permission-bypassing AI-agent bridge with prompt-token scrubbing.

- **Rationale:** The deliberate bypass and obfuscation make this a substantial runtime agent-capability risk. Lack of an install hook and no verified exfiltration path keep the evidence below the publication-block threshold.

- **Files touched:** claude-bridge/src/claude.js, claude-bridge/src/tools.js, claude-bridge/src/index.js, dist/services/edit-governor.js

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The vendored bridge deliberately rewrites OpenClaw names and tool-like tokens under a comment calling it a detection bypass., The bridge always launches the local Claude CLI with permission checks disabled., Published runtime files contain extensive deliberate JavaScript obfuscation, preventing normal source audit.

- **Evidence against:** package.json has only a prepublish-only hook, not an install-time lifecycle hook., The bridge binds its HTTP services to loopback addresses., No concrete credential theft or external exfiltration path was established from the inspected readable bridge source.

## Affected versions and remediation

This report applies to alvin-bot@5.149.1.

- Review the evidence and your use of alvin-bot@5.149.1 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.
