Treat them as untrusted evidence. 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:** 0.97.4 - **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. Source inspection found an explicit plugin setup capability that mutates agent configuration and can store Pod installer commands. Because it is user-invoked and no concrete attack behavior was established, warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-09T09:41:29.972Z - **Finished:** 2026-10-09T09:42:19.114Z - **Download time:** 1020 ms - **Static scan time:** 3344 ms - **AI review time:** 44777 ms - **Total time:** 49142 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 plugin command can add MCP server entries to local agent configuration and save installer instructions for remote Pods. This is an explicit setup capability; no concrete attack was established. - **Trigger:** A user runs \`h2a plugin add\`. - **Impact:** The registered MCP server or Pod installer can run with the corresponding agent or Pod privileges. - **Evidence paths:** dist/index.js, dist/plugin.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T09:42:19.114Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command installs or configures a plugin, registers its MCP server with agent CLIs, and can persist a supplied installer command for later Pod sync. - **Rationale:** Source inspection found an explicit plugin setup capability that mutates agent configuration and can store Pod installer commands. Because it is user-invoked and no concrete attack behavior was established, warn rather than block. - **Files touched:** ~/.codex/config.toml, ~/.gemini/config/mcp\_config.json, ~/.claude.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes a user-invoked plugin-add command that installs plugins and registers their MCP servers with agent CLIs., Plugin registration writes MCP configuration into the user's Codex configuration file., The explicit installer option can save a user-supplied shell command for execution in remote session Pods. - **Evidence against:** The inspected plugin setup is activated through the explicit \`h2a plugin add\` command; the package manifest shows no install lifecycle hook. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.97.4. - Review the evidence and your use of @sentropic/h2a-runtime@0.97.4 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: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** dist/central-mcp.js - **Public source:** [View source]() Package source references dynamic require/import behavior.

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: } ``` ### 6. 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"); } ``` ### 7.

High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** dist/launch-layout.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @sentropic/h2a-runtime@0.96.2 matchedIdentity = npm:QHNlbnRyb3BpYy9oMmEtcnVudGltZQ:0.96.2 similarity = 0.932 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 84.0% - **Path:** dist/plugin.js - **Public source:** [View source]() The package exposes a user-invoked plugin-add command that installs plugins and registers their MCP servers with agent CLIs.
