PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    skills/expo-skill-feedback/scripts/telemetry.cjs, line 57 try { fs.rmSync(OPT_IN_PATH, { force: true }); } catch {}

  • NETWORK_NO_FIXED_HOST Low

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

    skills/eas-app-stores/references/app-store-metadata.md, line 290 const translations = await fetch(

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/eas-app-stores/references/app-store-metadata.md, line 290 const translations = await fetch(

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/eas-simulator/references/run-your-app.md, line 18 # Start (the default --out-config-type dotenv writes .env.eas-simulator). It boots the sim + agent-device daemon.

  • SECRETS_ENV_READ Note

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

    skills/eas-hosting/SKILL.md, line 149 Authorization: `Bearer ${process.env.OPENAI_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.
