AI assistants receive package-authored instructions without separate setup consent, while installation runs without the targeted deletion safeguard. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.38 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Global npm installation automatically changes foreign AI-assistant skill directories. Installation subprocesses also strip a WorkBuddy safe-delete preload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-01T20:35:56.584Z - **Finished:** 2026-10-01T20:37:01.047Z - **Download time:** 1023 ms - **Static scan time:** 76 ms - **AI review time:** 63363 ms - **Total time:** 64463 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:** Global npm installation automatically changes foreign AI-assistant skill directories. Installation subprocesses also strip a WorkBuddy safe-delete preload. - **Trigger:** Global npm installation outside CI with GUAN\_SKIP\_INSTALL\_SKILL unset or different from 1. - **Impact:** AI assistants receive package-authored instructions without separate setup consent, while installation runs without the targeted deletion safeguard. - **Evidence paths:** package.json, bin/postinstall.js, bin/run.js, bin/install-env.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T20:37:01.047Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook invokes a globally targeted, automatically confirmed skill installer, then copies package skill files into CodeBuddy and WorkBuddy directories; child environments remove the safe-delete preload. - **Attack narrative:** A global installation launches install-skill automatically. That command invokes the skills installer with global and automatic-confirmation flags, then copies its skill into foreign assistant configuration directories. The installation environment explicitly strips WorkBuddy's safe-delete preload. The global-only gate and opt-out reduce exposure but do not provide affirmative consent or preserve the safeguard. - **Rationale:** The inspected lifecycle chain performs unconsented changes to foreign AI-agent control surfaces and explicitly disables a safety preload. These concrete behaviors exceed guarded package-owned extension setup and warrant blocking under the supplied policy. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** .codebuddy, .workbuddy, skills/guanetl ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json activates bin/postinstall.js automatically after installation., The hook runs during global installs unless CI or GUAN\_SKIP\_INSTALL\_SKILL disables it, invoking install-skill without affirmative consent., bin/run.js invokes skills add with automatic confirmation and global installation flags., After successful installation, the launcher copies the skill into CodeBuddy and WorkBuddy skill directories., bin/install-env.js removes the genie-safe-delete.cjs preload from NODE\_OPTIONS for installation subprocesses, disabling that safeguard. - **Evidence against:** Local installs and CI skip automatic skill installation, and an environment variable provides an opt-out., The installed skill belongs to this package; inspected JavaScript shows no credential exfiltration. ## Affected versions and remediation This report applies to @guandata/guanetl@0.1.38. - Avoid installing @guandata/guanetl@0.1.38. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
