Grade D

Two or more Medium findings, or a High finding. Only try it in a sandbox.

Graded by PlugVetRubric v2

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

Rescanned at commit b3f1f0918905, unchanged since the check below.

PERMISSION_SHELL_UNDECLARED OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    clients/python/scripts/check_package.py, line 35 subprocess.run(

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

    Contains a very long line with almost no spaces in a script or style file.

    package-lock.json, line 1 {

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.
