Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    find_all_keys.py, line 38 r = subprocess.run(["tasklist","/FI","IMAGENAME eq Weixin.exe","/FO","CSV","/NH"],

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 1 pycryptodome>=3.20.0

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    monitor_web.py, line 762 fetch('/api/history').then(r=>r.json()).then(ms=>{

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
