Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/check_engineering.py, line 57 result = subprocess.run( # noqa: S603 -- fixed read-only Git command, no shell

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/check_engineering.py, line 23 ENV_EXAMPLES = (".env.example", ".env.sample", ".env.template")

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

  • SECRETS_ENV_READ Note

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

    src/zai_passbolt/config.py, line 71 secret = Path(os.environ.get("PASSBOLT_SECRET_FILE", ""))

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.
