Grades are a hygiene check, not a security guarantee.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit b2e7d1f9dfeb, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/backup-db.js, line 41 await fs.unlink(localPath);

  • NETWORK_NO_FIXED_HOST Low

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

    packages/agent-billing/src/index.js, line 44 async fetch(request, env) {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    packages/agent-billing/src/index.js, line 44 async fetch(request, env) {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/autonomous-deploy.js, line 108 const envPath = path.join(process.cwd(), '.env');

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    package-lock.json, line 1 {

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    FINAL-DEPLOY.md, line 140 curl -s https://metamesh-uga.dev/install | bash -s -- --dry-run

  • SECRETS_ENV_READ Note

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

    scripts/autonomous-deploy.js, line 174 const key = crypto.scryptSync(process.env.BACKUP_PASSWORD || 'metamesh-backup-key', 'salt', 32);

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern
