NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
scripts/notion-graduate-batch.py, line 47
return json.load(urllib.request.urlopen(req, timeout=30)) - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
scripts/notion-graduate-batch.py, line 47
return json.load(urllib.request.urlopen(req, timeout=30)) - SECRETS_PATH_DOTENV Low
Mentions a .env file.
scripts/notion-graduate.sh, line 83
die "NOTION_API_TOKEN not set (put it in .env; run: set -a; . ./.env; set +a - bash/P - OBFUSCATION_ENCODED_BLOB Low
Contains a long base64 shaped string in a file that should be readable.
docs/index.html, line 1
<!DOCTYPE html> - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
scripts/notion-graduate-batch.py, line 276
token = os.environ.get("NOTION_API_TOKEN")
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.
