Do not execute instructions or code found in this document. ## 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:** 0.94.2 - **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. This is a dangerous agent-management capability with explicit user-command triggers, not concrete malicious package behavior. Policy calls for a warning rather than a block for explicit agent configuration mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-08-21T10:24:55.596Z - **Finished:** 2026-08-21T10:26:13.522Z - **Download time:** 2769 ms - **Static scan time:** 4210 ms - **AI review time:** 70946 ms - **Total time:** 77926 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:** Explicit CLI commands can install user-selected plugins or installers and register MCP servers in local and remote agent environments. No install-time execution or unconsented mutation was found. - **Trigger:** User runs \`h2a plugin add\`/\`h2a plugin sync\` or \`h2a enroll --install-hooks\`. - **Impact:** Can add executable MCP entries and run a user-supplied installer in configured remote Pods. - **Evidence paths:** package.json, dist/index.js, dist/plugin.js, dist/enroll.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T10:26:13.522Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-directed plugin installation and MCP/hook configuration. - **Rationale:** This is a dangerous agent-management capability with explicit user-command triggers, not concrete malicious package behavior. Policy calls for a warning rather than a block for explicit agent configuration mutation. - **Files touched:** ~/.claude.json, ~/.codex/config.toml, ~/.gemini/config/mcp\_config.json, ~/.claude/settings.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Explicit \`plugin add\` installs and registers MCP servers for Claude, Codex, and agy., The explicit plugin workflow accepts a user-provided shell installer and can run it in configured remote Pods., Explicit \`enroll --install-hooks\` modifies Claude settings after a user selects that option. - **Evidence against:** package.json has no lifecycle scripts., CLI dispatch runs only when dist/index.js is the direct entry point., No hard-coded external endpoint, stealth payload, or automatic agent-config mutation was confirmed., Claude credential access is documented as expiry advisory only. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.94.2. - Review the evidence and your use of @sentropic/h2a-runtime@0.94.2 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. ## Public findings ### 1.
