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 SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
projects/link-preview-api/automation-client/agent_client.py, line 14
calling code just does a normal `await http.get(...)`. - SECRETS_PATH_DOTENV Low
Mentions a .env file.
projects/content-moderation-api/api/app/config.py, line 5
changing env vars - see ../.env.example for every knob and what it does. - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
projects/content-moderation-api/api/app/config.py, line 59
cdp_api_key_id=os.environ.get("CDP_API_KEY_ID"),
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.
