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

Rescanned at commit 3f6bcea7c890, unchanged since the check below.

NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED

Why this grade

    skills/skills-save/scripts/discover-installed-plugins.sh, line 90 res = subprocess.run(

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.
