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

Rescanned at commit e0bb3c270d7f, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/merge-cli.ts, line 103 fs.unlinkSync(actualOutput);

  • NETWORK_NO_FIXED_HOST Low

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

    web/index.html, line 556 async function fetchGraph() { return (await fetch('/api/graph')).json(); }

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    .gitignore, line 7 *.log

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.
