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

Rescanned at commit c7fa6879d860, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/check-deadline-drift.ts, line 157 const res = await fetch(url, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/reporting/ga4DataApi.ts, line 45 * Secrets pasted into `.env` files or CI secret stores routinely arrive with

  • SECRETS_ENV_READ Note

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

    src/analytics.ts, line 40 const apiSecret = process.env.GA4_API_SECRET?.trim();

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    src/data/articlesDiscovered.ts, 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.
