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.
PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
deploy/railway-ci/run.py, line 103
subprocess.run( - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
scripts/verify_pages_ci.py, line 70
with urllib.request.urlopen(request, timeout=25) as response: - SECRETS_PATH_DOTENV Low
Mentions a .env file.
deploy/railway-ci/Dockerfile.dockerignore, line 6
.env - OBFUSCATION_ENCODED_BLOB Low
Contains a long base64 shaped string in a file that should be readable.
integrations/alpaca-paper/uv.lock, line 1
version = 1 - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
integrations/trading-copilot/deploy/capture_observatory.py, line 200
credential_directory = os.environ.get("CREDENTIALS_DIRECTORY")
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.
