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

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.

    api/acp.ts, line 264 resp = await fetch(

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    api/acp.ts, line 264 resp = await fetch(

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    lib/env.ts, line 16 `Set it in your deployment (Vercel project settings, .env.local, etc.).`

  • SECRETS_ENV_READ Note

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

    api/acp.ts, line 52 const key = process.env.SUPABASE_SERVICE_ROLE_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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern
