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

Rescanned at commit d9bb8e65f5a1, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_MINIFIED_PAYLOAD SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    docs/public/play/assets/index-xlL-kyPz.js, line 1 (l){if(l.ep)return;l.ep=!0;const i=n(l);fetch(l.href,i)}})();var Vs={exports:{}},Ml={}

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    docs/public/play/assets/index-xlL-kyPz.js, line 1 (l){if(l.ep)return;l.ep=!0;const i=n(l);fetch(l.href,i)}})();var Vs={exports:{}},Ml={}

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/live.ts, line 4 * Reads .env (FIGMA_TOKEN, PLUMB_FILE_KEY, PLUMB_NODE_ID).

  • OBFUSCATION_MINIFIED_PAYLOAD Low

    Contains a very long line with almost no spaces in a script or style file.

    package-lock.json, line 1 {

  • SECRETS_ENV_READ Note

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

    scripts/live.ts, line 15 const fileKey = process.env.PLUMB_FILE_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

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.
