The package can alter the instructions and available capabilities of installed AI-agent environments without an explicit user command. - **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:** 1.1.4 - **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. Installing the package triggers a postinstall script that writes a package-controlled AI skill into multiple unrelated agent control surfaces. It also falls back to a generic agent skill directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T00:31:36.554Z - **Finished:** 2026-09-13T00:32:21.427Z - **Download time:** 505 ms - **Static scan time:** 734 ms - **AI review time:** 43632 ms - **Total time:** 44873 ms The recorded confidence comes from the underlying analysis.

It also falls back to a generic agent skill directory. - **Trigger:** npm installation, including automatic postinstall execution - **Impact:** The package can alter the instructions and available capabilities of installed AI-agent environments without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T00:32:21.427Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-agent skill deployment - **Attack narrative:** During npm installation, package.json runs scripts/postinstall.js. That script detects several third-party AI-agent home directories and copies its bundled SKILL.md and references into each matching directory. It removes the prior references directory and, when none match, creates a generic ~/.agents/skills/tuniu-cli installation. This is an unconsented postinstall mutation of broad AI-agent control surfaces. - **Rationale:** The automatic lifecycle hook installs package-authored instructions into multiple foreign AI-agent directories and has a generic fallback. This meets the install-time AI-agent control-surface abuse policy even though the hook itself does not make network requests. - **Files touched:** skill/SKILL.md, skill/references, ~/.claude/skills/tuniu-cli, ~/.cursor/skills/tuniu-cli, ~/.codex/skills/tuniu-cli, ~/.config/opencode/skills/tuniu-cli, ~/.agents/skills/tuniu-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically runs the installer., The installer targets nine different AI-agent skill directories under the user's home directory., It copies the bundled skill and references into those directories, deleting existing bundled references first., On hosts without a detected agent directory, it still writes to the generic .agents skill directory. - **Evidence against:** The install hook uses a bundled local skill rather than downloading one., No credential collection or network request occurs in the postinstall script itself. ## Affected versions and remediation This report applies to tuniu-cli@1.1.4. - Avoid installing tuniu-cli@1.1.4. 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.
