Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit 8525664b324b, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    evals/doc_scan.py, line 36 n_cases = len(subprocess.run(

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/lit_api.py, line 549 with urllib.request.urlopen(req, timeout=SOCKET_TIMEOUT) as r:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    evals/mutation_check.py, line 298 ("cite_integrity 不讀 .env → .env 裡的 LIT_LANG 對它無效", "cite_integrity.py",

  • SECRETS_ENV_READ Note

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

    evals/mutation_check.py, line 254 ' if _s2_429_seen and not os.environ.get("S2_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.
