A user-approved installer deploys an auto-loaded Hermes plugin. On a guarded first interactive LLM turn, that plugin can fetch the latest npm version and replace its own installed payload via npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-09T01:48:24.223Z - **Finished:** 2026-08-09T01:49:14.255Z - **Download time:** 504 ms - **Static scan time:** 628 ms - **AI review time:** 48899 ms - **Total time:** 50032 ms ## Security analysis ### Published attack-surface review - **Summary:** A user-approved installer deploys an auto-loaded Hermes plugin. On a guarded first interactive LLM turn, that plugin can fetch the latest npm version and replace its own installed payload via npx. - **Trigger:** Explicit lithermes install --yes, followed by the first eligible interactive Hermes pre\_llm\_call turn. - **Impact:** A newly published package version can execute through the Hermes plugin and modify the installed Hermes extension/config; optional compatibility patching can alter host source. - **Evidence paths:** package.json, src/cli.js, src/lib/install.js, src/lib/updateNotifier.js, src/lib/patch.js, assets/lithermes-plugin/auto\_update.py, assets/lithermes-plugin/plugin.yaml - **Review source:** ai\_review - **Reviewed:** 2026-08-09T01:49:14.255Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded remote self-update of a first-party AI-agent extension - **Rationale:** No install-time malware or exfiltration was found, but the package creates a guarded automatic remote-update path for an AI-agent extension and optionally patches host code. This is a real lifecycle/control-surface risk, not evidence of malicious intent. - **Files touched:** assets/lithermes-plugin/auto\_update.py, $HERMES\_HOME/plugins/lithermes, $HERMES\_HOME/config.yaml, $HERMES\_HOME/lithermes/auto-update-receipt.json, $HERMES\_HOME/hermes-agent/cli.py, $HERMES\_HOME/hermes-agent/gateway/run.py, $HERMES\_HOME/hermes-agent/hermes\_cli/plugins.py - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** assets/lithermes-plugin/auto\_update.py runs on pre\_llm\_call and invokes npx for a newer registry version., src/lib/updateNotifier.js downloads registry metadata then runs npx \ install --yes., src/lib/install.js copies an auto-loaded plugin and edits Hermes config., src/lib/patch.js can modify Hermes CLI, gateway, and plugin-loader source after installation. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Installation requires the user to run install with --yes., Auto-update is restricted to first interactive top-level turns and supports opt-out., Update code uses a fixed npm-registry endpoint, reduced environment, timeout, backup, rollback, and doctor check., No credential harvesting or non-registry exfiltration was found in inspected paths. ## Public findings ### 1.
