## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 29 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 5.120.1
- **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 package has no automatic install lifecycle, but source code establishes an unresolved runtime command-injection path plus deliberate permission-bypass and concealment behavior. This warrants a warning rather than an install-hook block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-09-05T08:57:37.352Z
- **Finished:** 2026-09-05T08:59:04.519Z
- **Download time:** 258 ms
- **Static scan time:** 8874 ms
- **AI review time:** 78031 ms
- **Total time:** 87167 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:** A runtime bridge disables Claude permission checks and an email plugin constructs shell commands from chat arguments. This is a concrete command-injection and unsafe agent-control risk, not an install-time attack.

- **Trigger:** Start the bot and send an email read command to an enabled email plugin.

- **Impact:** An authorized or otherwise admitted chat sender could execute shell syntax through the email command; the bridge also weakens agent permission safeguards.

- **Evidence paths:** claude-bridge/src/claude.js, claude-bridge/src/server.js, plugins/email/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-05T08:59:04.519Z

### AI review details

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

- **Mechanism:** Shell interpolation of a chat argument and permission-bypassing Claude invocation.

- **Rationale:** The package has no automatic install lifecycle, but source code establishes an unresolved runtime command-injection path plus deliberate permission-bypass and concealment behavior. This warrants a warning rather than an install-hook block.

- **Files touched:** claude-bridge/src/claude.js, claude-bridge/src/server.js, plugins/email/index.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

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

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for warning:** The Claude bridge deliberately labels token replacement as a detection bypass., The bridge starts Claude with its permission checks disabled., The email command passes a chat-controlled message identifier directly into a shell command., The bridge automatically deletes old Claude session files at startup.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook; its only lifecycle hook is prepublishOnly., No source inspected showed secret collection or transmission to an attacker-controlled endpoint.

## Affected versions and remediation

This report applies to alvin-bot@5.120.1.

- Review the evidence and your use of alvin-bot@5.120.1 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.
