Rescanned at commit 63bd5ba686b4.

INSTALL_REMOTE_SCRIPT PERMISSION_SHELL_UNDECLARED SECRETS_PATH_CREDENTIAL

Why this grade

  • INSTALL_REMOTE_SCRIPT High

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    src/sentinelx_core/platform_guidance.py, line 153 "curl -fsSL https://get.sentinelx.app | bash",

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    src/sentinelx_core/client.py, line 91 out = subprocess.run(args, capture_output=True, text=True, timeout=3)

  • SECRETS_PATH_CREDENTIAL Medium

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

    THREAT_MODEL.md, line 30 | Operator credentials transiting through tools | e.g., `cat ~/.aws/credentials` if allowed | Direct credential theft |

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.

  • Network

    Concern

    with urllib.request.urlopen(req, timeout=30) as resp:

    src/sentinelx_core/handlers/basic.py, line 350

    "the hub over an authenticated WebSocket (no inbound ports), runs "
