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

Rescanned at commit fb1de30fda06, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/spicebridge/circuit_manager.py, line 69 shutil.rmtree(evict_state.output_dir, ignore_errors=True)

  • NETWORK_NO_FIXED_HOST Low

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

    start_cloud.sh, line 31 echo " Debian/Ubuntu: curl -fsSL https://pkg.cloudflare.com/cloudflare-main.gpg | sudo tee /usr/share/keyrings/cloudflare-main.gpg >/dev/null"

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    start_cloud.sh, line 31 echo " Debian/Ubuntu: curl -fsSL https://pkg.cloudflare.com/cloudflare-main.gpg | sudo tee /usr/share/keyrings/cloudflare-main.gpg >/dev/null"

  • SECRETS_PATH_UNCONFIRMED Low

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

    src/spicebridge/__main__.py, line 94 api_key = os.environ.get("SPICEBRIDGE_API_KEY", "")

  • SECRETS_ENV_READ Note

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

    src/spicebridge/__main__.py, line 94 api_key = os.environ.get("SPICEBRIDGE_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.
