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

NETWORK_HOST_FROM_INPUT SECRETS_PATH_CREDENTIAL OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • NETWORK_HOST_FROM_INPUT High

    A file takes a URL or endpoint as input and has no fixed host list.

    src/holocore/animus_retrieval.py, line 42 with urllib.request.urlopen(request, timeout=self.timeout) as response:

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    .gitignore, line 50 credentials.json

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

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

    src/holocore/atlas_html.py, line 44 :root{color-scheme:dark;font-family:"IBM Plex Sans","Segoe UI",system-ui,sans-serif;background:#0f172a;color:#f8fafc;--panel:#111c30;--line:#334155;--muted:#a8b4c5;--focus:#38bdf8;

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.
