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

Rescanned at commit 473586fa8e57, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/tutor-server.js, line 238 fs.unlinkSync(serverStoppedPath);

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/test-server.sh, line 49 BODY=$(curl -s "$BASE_URL")

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.
