Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    README.md, line 124 The server never loads a `.env` file automatically. Never commit credentials. Steam profile and game-details privacy settings can prevent account tools from returning data; local c

  • SECRETS_ENV_READ Note

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

    src/server.ts, line 8 const defaultApi = new SteamApiClient({ apiKey: process.env.STEAM_API_KEY, steamId: process.env.STEAM_ID }, cache);

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.
