Grade B

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

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

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skills/sumsub-api-auth/scripts/sumsub_curl.sh, line 69 curl "${CURL_ARGS[@]}" "${BASE}${PATH_Q}"

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/sumsub-api-auth/SKILL.md, line 58 # .env

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    skills/sumsub-conformance/scripts/resolve_graph.sh, line 53 out = subprocess.run(["bash", curl, "GET", path], capture_output=True, text=True)

  • SECRETS_ENV_READ Note

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

    skills/sumsub-api-auth/scripts/sumsub_sign.py, line 45 token = os.environ.get("SUMSUB_APP_TOKEN", "").strip()

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    skills/sumsub-create-workflow/references/workflow-expressions.md, line 1 # Workflow expression reference

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.
