A loaded Hermes plugin can automatically retrieve and execute a newer lithermes-ai release. Its installer changes the user's Hermes plugin and configuration, and may patch detected Hermes files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-31T05:02:06.955Z - **Finished:** 2026-08-31T05:03:08.313Z - **Download time:** 512 ms - **Static scan time:** 1097 ms - **AI review time:** 59748 ms - **Total time:** 61358 ms ## Security analysis ### Published attack-surface review - **Summary:** A loaded Hermes plugin can automatically retrieve and execute a newer lithermes-ai release. Its installer changes the user's Hermes plugin and configuration, and may patch detected Hermes files. - **Trigger:** A first interactive top-level Hermes CLI turn after the plugin has been installed. - **Impact:** A registry-delivered newer package can change the installed agent extension and Hermes environment without a separate update command. - **Evidence paths:** assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, src/lib/install.js, src/lib/patch.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T05:03:08.313Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Pre-LLM auto-update invokes an exact newer npm release through npx. - **Rationale:** The package creates an automatic registry-to-npx update path from a loaded AI-agent hook and mutates the agent environment. The behavior is concrete but does not establish malicious theft or destructive intent in this release. - **Files touched:** ~/.hermes/config.yaml, ~/.hermes/lithermes, \/cli.py, \/gateway/run.py, \/hermes\_cli/plugins.py - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The installed plugin auto-loads a pre-LLM hook., That hook fetches a newer registry version and runs it through npx without a new user command., The installer can copy a plugin and modify Hermes configuration and detected Hermes source files. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The only observed network target is the package's npm registry endpoint., No source evidence shows credential collection or exfiltration. ## Public findings ### 1.
