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

Rescanned at commit cf22892f67b8, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/garmin/auth.ts, line 59 fs.unlinkSync(sessionPath);

  • NETWORK_NO_FIXED_HOST Low

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

    src/cli.ts, line 638 console.log(" curl against /api/watch with the key looks the same from here.");

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/generate-store-screenshots.ps1, line 55 $apiKeyLine = Get-Content ".env" | Where-Object { $_ -match "^TRAINBUD_API_KEY=" }

  • SECRETS_ENV_READ Note

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

    scripts/generate-store-screenshots.ps1, line 55 $apiKeyLine = Get-Content ".env" | Where-Object { $_ -match "^TRAINBUD_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.
