Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source shows a package-aligned conversion workflow, but it also fetches an executable during postinstall and runs it during conversion; the binary’s behavior could not be inspected through the source reader. This supports a warning for unresolved executable risk, not a finding of malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-08T09:40:41.808Z - **Finished:** 2026-10-08T09:41:21.254Z - **Download time:** 774 ms - **Static scan time:** 291 ms - **AI review time:** 38381 ms - **Total time:** 39446 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:** The postinstall hook downloads a Windows executable from the project’s GitHub repository. On Windows, the converter can run that executable when a caller requests DOCX-to-PDF conversion; no separate malicious behavior was established from the inspected source. - **Trigger:** Package installation triggers the download; a caller invoking Microsoft Office conversion on Windows triggers execution. - **Impact:** This introduces a remotely fetched executable into the installed package and runs it during requested conversion, creating unresolved executable supply-chain risk. - **Evidence paths:** package.json, scripts/install.mjs, src/downloadFiles.mjs, src/WDocx2pdf.mjs, dist/w-docx2pdf.umd.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T09:41:21.254Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes cv.exe under the package source directory, and the converter passes it DOCX and PDF paths through its process helper. - **Rationale:** The source shows a package-aligned conversion workflow, but it also fetches an executable during postinstall and runs it during conversion; the binary’s behavior could not be inspected through the source reader. This supports a warning for unresolved executable risk, not a finding of malicious intent. - **Files touched:** src/cv.exe - **Network endpoints:** https://github.com/yuda-lyu/w-docx2pdf/raw/refs/heads/master/src/cv.exe ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall script that downloads a Windows executable from a GitHub URL into the package source directory., The converter selects that executable and runs it on Windows when Microsoft Office mode is used. - **Evidence against:** The executable supports the package’s stated DOCX-to-PDF purpose and runs only when conversion is invoked on Windows., The installer limits the download to installations where the package path includes node\_modules. ## Affected versions and remediation This report applies to w-docx2pdf@1.0.17. - Review the evidence and your use of w-docx2pdf@1.0.17 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
