Rescanned at commit d2c7c4215029, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    release.sh, line 86 curl -sSL "$url" -o "$cache/mcp-publisher.tar.gz" || die "Failed to download mcp-publisher"

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    release.sh, line 86 curl -sSL "$url" -o "$cache/mcp-publisher.tar.gz" || die "Failed to download mcp-publisher"

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 25 .env

  • SECRETS_ENV_READ Note

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

    src/cli.ts, line 38 const API_KEY = process.env.FHIRFLY_API_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.
