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. Source inspection found explicit commands that install plugins and update agent configuration, but no npm lifecycle hook that performs these actions automatically. This is a warning-level agent capability, not evidence of malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T09:41:03.420Z - **Finished:** 2026-10-09T09:41:52.768Z - **Download time:** 1011 ms - **Static scan time:** 3343 ms - **AI review time:** 44993 ms - **Total time:** 49348 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:** The runtime provides user-invoked commands that can install plugins and modify agent configuration. No confirmed attack surface was established because the reviewed changes are command-triggered and there is no install lifecycle hook. - **Trigger:** A user invokes the plugin command or explicitly requests Claude hook installation. - **Impact:** These actions can change agent behavior and add plugin capabilities, with effects limited to the user-requested setup. - **Evidence paths:** dist/plugin.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T09:41:52.768Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin command installs the selected package globally and registers its MCP configuration in agent settings; the hook option merges hooks into Claude settings. - **Rationale:** Source inspection found explicit commands that install plugins and update agent configuration, but no npm lifecycle hook that performs these actions automatically. This is a warning-level agent capability, not evidence of malicious behavior. - **Files touched:** dist/plugin.js, dist/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest exposes the runtime entrypoint and declares no lifecycle script., Plugin installation is initiated through the explicit plugin CLI command and installs the selected package globally., The plugin command registers MCP configuration in agent configuration files, including Codex configuration., Hook installation is an explicit option that merges hooks into Claude settings., The reviewed auth helper collects selected local tool authentication files for remote sessions; this is deployment functionality, not evidence of theft., No concrete malicious behavior was identified; the configuration and plugin changes are user-invoked capabilities. - **Evidence against:** The plugin command can install a package globally and write behavior-bearing agent configuration, so this is a concrete capability requiring user invocation., The manifest has no npm install lifecycle hook that would trigger the observed setup automatically. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.95.0. - Review the evidence and your use of @sentropic/h2a-runtime@0.95.0 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. ## Public findings ### 1. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 2. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** dist/pty.js - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = @sentropic/h2a-runtime; repositoryIdentity = h2a; dependency = node-pty L76: try { L77: require("node-pty"); L78: } ``` ### 5. High: External Ai Agent Control Surface Mutation - **Category:** Source - **Confidence:** 94.0% - **Path:** dist/plugin.js - **Public source:** [View source]() Runtime or CLI source writes behavior-bearing configuration into a user or project AI-agent control surface. Public source snippet (untrusted): ```javascript Runtime or CLI code links a write operation to an explicit external AI-agent control path: nd, args: [...args] }; root.mcpservers = servers; return json.stringify(root, null, 2) + "\n"; } export function mergeclaudemcpservers(json, name, command, args) { return mergemcpserversjson(json, name, command, args, "claude.json"); } export function mergeagymcpservers(json, name, command, args) { return mergemcpserversjson(json, name, command, args, "mcp_config.json"); } ``` ### 6.
