## Security analysis

### Published attack-surface review

- **Summary:** Installation downloads an executable from a mutable GitHub branch into the consuming project's src directory. A later document-conversion call executes that downloaded binary.

- **Trigger:** npm postinstall, followed by WDocx2pdf MicrosoftOffice conversion

- **Impact:** A changed remote binary can execute with the user's privileges when conversion is invoked.

- **Evidence paths:** package.json, scripts/install.mjs, src/downloadFiles.mjs, src/WDocx2pdf.mjs, srcPython/cv.py

- **Review source:** ai\_review

- **Reviewed:** 2026-08-10T17:23:08.806Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** unpinned remote executable staging and runtime execution

- **Rationale:** This is not proven intentional malware, but it stages an unverified remote executable during installation outside its package directory and later runs it. Warn until the executable is packaged and integrity-pinned.

- **Files touched:** package.json, scripts/install.mjs, src/downloadFiles.mjs, src/WDocx2pdf.mjs, src/cv.exe

- **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:** package.json runs postinstall, scripts/install.mjs invokes download on npm install, src/downloadFiles.mjs fetches unpinned master cv.exe, download target resolves to project src/cv.exe, src/WDocx2pdf.mjs executes cv.exe at runtime

- **Evidence against:** srcPython/cv.py is a docx2pdf conversion wrapper, No credential harvesting or exfiltration found, No AI-agent/configuration manipulation found
