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

Rescanned at commit b127449f3108, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/core/logger.ts, line 36 if (fs.existsSync(oldest)) fs.unlinkSync(oldest);

  • NETWORK_NO_FIXED_HOST Low

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

    src/core/billing/stripe.ts, line 69 const res = await fetch(`${STRIPE_API}/checkout/sessions`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/core/billing/stripe.ts, line 69 const res = await fetch(`${STRIPE_API}/checkout/sessions`, {

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    src/core/billing/stripe.ts, line 18 const _secretKey = process.env.STRIPE_SECRET_KEY;

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/core/billing/stripe.ts, line 18 const _secretKey = process.env.STRIPE_SECRET_KEY;

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.
