That release replaces the agent plugin and modifies Hermes configuration without a fresh user confirmation. - **Trigger:** An interactive first LLM call after the plugin has been installed, when a newer registry version exists. - **Impact:** A registry-selected newer package release gains automatic execution and can alter the Hermes agent control surface. - **Evidence paths:** assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, src/cli.js, src/lib/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T02:57:06.374Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hidden pre-LLM self-update through npx followed by plugin and config replacement. - **Attack narrative:** After installation, the auto-loaded plugin registers pre\_llm\_call. On a first interactive turn it queries the npm registry and runs npx against a newer exact lithermes-ai release through a private command hidden from normal help. The child installer removes the current plugin payload, copies its replacement, and writes Hermes configuration. This is an automatic runtime self-dependency chain that changes an AI-agent control surface without a fresh user action. - **Rationale:** The package contains a concealed automatic self-update path from an AI-agent lifecycle hook to a newer release of itself, followed by control-surface mutation. Although it lacks an npm install hook and limits inherited environment variables, the complete hidden self-update chain is concrete and automatic. - **Files touched:** ~/.hermes/plugins/lithermes, ~/.hermes/config.yaml, ~/.hermes/lithermes/install-manifest.json - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The installed plugin registers a pre-LLM lifecycle hook, so update code runs during agent use., The hook fetches the latest version and silently invokes npx for a newer release of this same package., The private update command is deliberately omitted from help output., The invoked installer replaces the LitHermes plugin payload and writes Hermes configuration without a new user confirmation., The package contacts the npm registry as part of this automatic self-update chain. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle script., The update child process removes most inherited environment variables, limiting direct credential exposure., The shown update path requests an exact stable version and includes rollback checks. ## Public findings ### 1.
