Compatibility: Not stated.
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.

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.
