Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Package installation can alter instructions supplied to AI coding tools in the consumer project. - **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:** 0.0.8 - **Selected version is latest:** No - **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. The package performs concrete, unconsented postinstall writes to consumer AI-agent configuration paths. Although no exfiltration or remote payload execution is present, this meets the firewall block boundary for foreign AI-agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-07-11T22:07:53.766Z - **Finished:** 2026-07-11T22:09:00.308Z - **Download time:** 510 ms - **Static scan time:** 220 ms - **AI review time:** 65811 ms - **Total time:** 66542 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:** Install-time code mutates AI-agent control directories in the consuming project without a user command. It conditionally writes a package-authored instruction document into Kiro or Cursor configuration paths. - **Trigger:** npm installation runs the package \`postinstall\` hook. - **Impact:** Package installation can alter instructions supplied to AI coding tools in the consumer project. - **Evidence paths:** package.json, scripts/postinstall.js, docs/implement-tantuui-token-and-component.md, dist/index.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-07-11T22:09:00.308Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes AI guidance into consumer \`.kiro/steering\` or \`.cursor/rules\` paths. - **Attack narrative:** During \`postinstall\`, the package determines the consuming project root and copies its bundled AI usage guide into existing Kiro or Cursor instruction directories, otherwise into \`docs/\`. This is an unconsented install-time mutation of foreign AI-agent control surfaces; it does not need network access to influence future agent behavior in that project. - **Rationale:** The package performs concrete, unconsented postinstall writes to consumer AI-agent configuration paths. Although no exfiltration or remote payload execution is present, this meets the firewall block boundary for foreign AI-agent control-surface mutation. - **Files touched:** package.json, scripts/postinstall.js, docs/implement-tantuui-token-and-component.md, .kiro/steering/implement-tantuui-token-and-component.md, .cursor/rules/implement-tantuui-token-and-component.md, docs/implement-tantuui-token-and-component.md ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** \`package.json\` runs \`node scripts/postinstall.js\` on install., \`scripts/postinstall.js\` locates the consumer project through \`INIT\_CWD\` or parent traversal., The lifecycle script writes an AI guidance document into existing \`.kiro/steering\` or \`.cursor/rules\` directories., The script creates \`docs/\` as fallback and suppresses lifecycle failure with \`|| true\`. - **Evidence against:** No network, credential harvesting, shell execution, dynamic code evaluation, or binary loading was found., \`dist/index.js\` and \`dist/index.cjs\` import only React, React DOM, and JSX runtime., The copied document is a TantuUI usage guide rather than an executable payload. ## Affected versions and remediation This report applies to @tantuui/react@0.0.8. - Avoid installing @tantuui/react@0.0.8. 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.
