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. No malicious automatic execution chain was found, but explicit commands modify AI-agent configuration and can register executable MCP servers. Policy classifies this first-party, user-invoked capability as warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-07-19T15:10:48.114Z - **Finished:** 2026-07-19T15:11:49.498Z - **Download time:** 1014 ms - **Static scan time:** 2129 ms - **AI review time:** 58240 ms - **Total time:** 61384 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/register MCP plugins and configure local agent clients. Explicit LLM-mesh enrollment can read local provider credentials for a user-run gateway. - **Trigger:** User runs h2a plugin/enroll/llm-mesh commands. - **Impact:** Can add MCP execution entries and handle provider tokens under the invoking user's account. - **Evidence paths:** package.json, dist/index.js, dist/plugin.js, dist/enroll.js, dist/llm-mesh.js - **Review source:** ai\_review - **Reviewed:** 2026-07-19T15:11:49.498Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked agent configuration and credential-backed gateway management. - **Rationale:** No malicious automatic execution chain was found, but explicit commands modify AI-agent configuration and can register executable MCP servers. Policy classifies this first-party, user-invoked capability as warn rather than block. - **Files touched:** ~/.claude.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/auth.json, ~/.sentropic/llm-mesh.json - **Network endpoints:** https://oauth2.googleapis.com/token, https://auth.openai.com/oauth/token, https://api.openai.com, https://api.anthropic.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** dist/plugin.js registers MCP servers in Claude, Codex, and Gemini config files., dist/index.js exposes explicit plugin add/sync commands, including user-supplied shell or HTTPS installer options., dist/llm-mesh.js reads local Codex, Claude, and Gemini credentials and persists gateway account data., dist/llm-mesh.js refreshes enrolled OAuth credentials against provider token endpoints. - **Evidence against:** package.json has no lifecycle scripts., dist/index.js runs main only when invoked as its entrypoint; imports do not start the CLI., Agent-config writes require explicit plugin or enroll command actions., No covert exfiltration, remote payload fetch-and-execute, or install-time mutation was found. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.85.19. - Review the evidence and your use of @sentropic/h2a-runtime@0.85.19 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.
