## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.21.21
- **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 inspected sources show a default-enabled project plugin execution capability, but no evidence that the package installs a malicious plugin or that its install hook mutates agent configuration. This warrants a warning for the conditional extension risk.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 78.0%
- **Started:** 2026-10-19T13:51:35.627Z

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:** Project hook plugins can run JavaScript automatically when hook events are dispatched, and plugin dispatch is enabled by default. This is a conditional extension capability; the inspected sources do not establish a package-installed malicious plugin.

- **Trigger:** A hook event is dispatched while a project contains plugin files in .omx/hooks.

- **Impact:** A plugin’s code can run with the permissions of the CLI process, creating risk if an untrusted project plugin is present.

- **Evidence paths:** dist/hooks/extensibility/dispatcher.js, dist/hooks/extensibility/loader.js, dist/hooks/extensibility/plugin-runner.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T13:55:04.918Z

### AI review details

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

- **Mechanism:** The dispatcher discovers project plugins and a child runner imports each module and invokes its event handler; users can disable ordinary plugin dispatch with an environment setting.

- **Rationale:** The inspected sources show a default-enabled project plugin execution capability, but no evidence that the package installs a malicious plugin or that its install hook mutates agent configuration. This warrants a warning for the conditional extension risk.

- **Files touched:** dist/hooks/extensibility/dispatcher.js, dist/hooks/extensibility/loader.js, dist/hooks/extensibility/plugin-runner.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 78.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Hook dispatch is enabled by default unless disabled, and native or derived events can force it on., The dispatcher discovers project hook plugins and the runner imports each plugin module before calling its event handler., The npm postinstall hook delegates to a script that skips local installs; global installs hydrate the native runtime., Agent setup is dispatched through the explicit CLI setup command.

- **Evidence against:** The inspected lifecycle source describes runtime hydration and install-stamp handling, not hook-plugin creation or agent setup., The plugin loader discovers files in the project’s .omx/hooks directory; the inspected sources do not show the package creating plugins there.

## Affected versions and remediation

This report applies to oh-my-codex@0.21.21.

- Review the evidence and your use of oh-my-codex@0.21.21 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.
