The installed Hermes plugin performs a guarded automatic self-update during an interactive pre-LLM hook. It queries npm and executes a registry-selected package version, which can replace the installed agent extension. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-11T09:29:54.420Z - **Finished:** 2026-08-11T09:30:58.116Z - **Download time:** 756 ms - **Static scan time:** 855 ms - **AI review time:** 62083 ms - **Total time:** 63696 ms ## Security analysis ### Published attack-surface review - **Summary:** The installed Hermes plugin performs a guarded automatic self-update during an interactive pre-LLM hook. It queries npm and executes a registry-selected package version, which can replace the installed agent extension. - **Trigger:** First interactive top-level Hermes turn after the plugin is installed, when an update is available. - **Impact:** A future registry package version gains execution and can modify the Hermes plugin/config without a fresh user command. - **Evidence paths:** package.json, assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, assets/lithermes-plugin/core.py, src/lib/updateNotifier.js, src/lib/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T09:30:58.116Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hook-triggered npm update and package-owned extension replacement. - **Rationale:** Source inspection found a real guarded agent-extension lifecycle risk from automatic registry-driven updates, not concrete malicious behavior. The package should warn rather than block. - **Files touched:** assets/lithermes-plugin/auto\_update.py, assets/lithermes-plugin/core.py, src/lib/updateNotifier.js, src/lib/install.js - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Plugin hook auto-fetches npm latest version on a first interactive Hermes turn., It runs \`npx --yes lithermes-ai@\\` without a new user command., Automatic transaction replaces the Hermes plugin and config after registry-selected update., Installer can patch Hermes host source when a repository is detected. - **Evidence against:** No npm install/preinstall/postinstall lifecycle hook is declared., Initial install requires explicit \`lithermes install --yes\`., Update paths sanitize inherited environment and exclude token-bearing npm settings., Registry response, versions, timeout, backup, rollback, and doctor checks are bounded. ## Public findings ### 1.
