Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No concrete attack was identified, but the package loads native binaries whose behavior remains unresolved. - **Trigger:** Package installation or importing its entrypoint. - **Impact:** The native code runs with the process's permissions; the available analysis does not establish what it does. - **Evidence paths:** package.json, index.js, .lpm-dependency-evidence-9a64c0a2-7fa7-4c29-8605-d3bd0a601a0f/0/npm-linux/node-gyp-build.js, .lpm-dependency-evidence-9a64c0a2-7fa7-4c29-8605-d3bd0a601a0f/0/npm-linux/bin.js, .lpm-inspection-d7bdtc/0-5b7a0f53f2ec.txt, .lpm-inspection-d7bdtc/1-1fdd50b1bf66.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-28T09:33:24.453Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The binding helper selects a platform-specific native module and loads it into the process. - **Rationale:** The install hook and runtime entrypoint can load bundled native modules, but inspection did not resolve their behavior: the Windows analysis is partial and the Linux artifact is unsupported. No specific attack was established, so this needs manual review rather than a malicious verdict. - **Files touched:** prebuilds/win32-x64/node.napi.node, prebuilds/linux-x64/node.napi.node ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package postinstall runs the native binding helper, which checks for a usable build., The package entrypoint also loads the native binding helper when imported., The helper loads the selected native module; the Windows artifact analysis leaves call targets uninspected., The Linux artifact is executable, but its behavior could not be structurally analyzed. - **Evidence against:** The inspected JavaScript selects and loads native builds; it contains no identified network or credential-transfer behavior., The package build configuration lists no source files. ## Affected versions and remediation This report applies to @testsecuiitytestme/cache-helper@1.0.3. - Avoid installing @testsecuiitytestme/cache-helper@1.0.3. 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.
