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

Rescanned at commit f7942cb36be3, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/clients/spio-api-client.ts, line 175 response = await fetch(`${this.baseUrl}/${endpoint}`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/config/environment.ts, line 8 config({ path: resolve(projectRoot, ".env") });

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.
