Normal Windows DOCX conversion later executes that executable. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-18T19:26:22.871Z - **Finished:** 2026-08-18T19:27:04.954Z - **Download time:** 507 ms - **Static scan time:** 425 ms - **AI review time:** 41151 ms - **Total time:** 42083 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation fetches a Windows executable from a mutable remote branch without a pinned hash. Normal Windows DOCX conversion later executes that executable. - **Trigger:** npm install, followed by calling WDocx2pdf in MicrosoftOffice mode on Windows - **Impact:** A changed remote cv.exe can execute with the privileges of the conversion caller. - **Evidence paths:** package.json, scripts/install.mjs, src/downloadFiles.mjs, src/WDocx2pdf.mjs, srcPython/cv.py - **Review source:** ai\_review - **Reviewed:** 2026-08-18T19:27:04.954Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote binary download followed by runtime native execution - **Rationale:** No concrete malicious payload behavior is present in the inspected source, but the package installs an unpinned remote executable and later executes it. This is a material staged-payload supply-chain risk. - **Files touched:** scripts/install.mjs, src/downloadFiles.mjs, src/cv.exe, src/WDocx2pdf.mjs - **Network endpoints:** https://github.com/yuda-lyu/w-docx2pdf/raw/refs/heads/master/src/cv.exe ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall downloads cv.exe from a mutable GitHub master URL into the installed package., The conversion API executes the downloaded cv.exe with user-provided document paths. - **Evidence against:** Source shows the executable is intended for Windows DOCX-to-PDF conversion., No source evidence of credential harvesting, unrelated file collection, or AI-agent control-surface mutation. ## Public findings ### 1.
