It can modify AI-agent control surfaces and place package-provided skills across installed clients. - **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:** 2.0.5 - **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. Installation automatically distributes remote skills into broad AI-agent skill directories. No user command or per-client consent gate is required. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-22T03:23:00.781Z - **Finished:** 2026-09-22T03:32:00.106Z - **Download time:** 763 ms - **Static scan time:** 893 ms - **AI review time:** 537668 ms - **Total time:** 539325 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:** Installation automatically distributes remote skills into broad AI-agent skill directories. No user command or per-client consent gate is required. - **Trigger:** npm postinstall execution. - **Impact:** It can modify AI-agent control surfaces and place package-provided skills across installed clients. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/bundle.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T03:32:00.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes skillshub.install with --force; the bundled CLI selects a fallback agent directory and detected client directories. - **Attack narrative:** Installing the package triggers its postinstall hook. The hook force-installs multiple skills through the bundled CLI. That CLI resolves broad AI-agent skill locations, including a default .agents directory and detected client directories such as Claude and WorkBuddy, enabling unconsented cross-client agent-surface modification. - **Rationale:** The automatic lifecycle hook force-writes skills to foreign and broad AI-agent control surfaces. This is concrete install-time control-surface hijacking. - **Files touched:** package.json, scripts/postinstall.cjs, dist/bundle.js - **Network endpoints:** https://skillshub.yunke.ai ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs scripts/postinstall.cjs automatically on installation., The postinstall script invokes the bundled CLI with --force for eight skills., The bundled installer targets .agents/skills by default and detected directories for multiple AI clients, including Claude and WorkBuddy. ## Affected versions and remediation This report applies to @yunkeai/yunke-cli@2.0.5. - Avoid installing @yunkeai/yunke-cli@2.0.5. 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.
