The source reads a parent-relative file and supplies its contents to a detached Node interpreter. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 90.0% - **Started:** 2026-08-19T09:29:04.335Z - **Finished:** 2026-08-19T09:30:06.458Z - **Download time:** 509 ms - **Static scan time:** 45 ms - **AI review time:** 61568 ms - **Total time:** 62123 ms ## Security analysis ### Published attack-surface review - **Summary:** The install lifecycle targets \`apps\`, whose index source is an external-file payload launcher. The source reads a parent-relative file and supplies its contents to a detached Node interpreter. - **Trigger:** npm postinstall, if the \`apps\` entry resolves and runs - **Impact:** Potential local code execution from a file outside the package boundary; execution is not confirmed due to the manifest/module mismatch. - **Evidence paths:** package.json, apps/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-19T09:30:06.458Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** external-file content piped into detached Node - **Rationale:** The package contains a concrete install-time staged-payload launcher, but source facts do not establish that its malformed/ambiguous entrypoint executes successfully. Warn rather than block. - **Files touched:** apps/index.js, ../../../public/logo.svg ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Install hook invokes Node on \`apps\`., \`apps/index.js\` reads \`../../../public/logo.svg\`, outside the package root., It pipes that file's contents to a detached Node process and unreferences it. - **Evidence against:** No network or credential-exfiltration code was found., The root manifest does not declare ESM mode although the lifecycle source uses ESM imports, so successful execution is not confirmed by source alone. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node apps ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node apps ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 6. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 7. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Install hook invokes Node on \`apps\`.
