NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low

const response = await fetch(url, { headers }); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
typescript-example/client/index.ts, line 13
dotenv.config(); // load environment variables from .env - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
typescript-example/client/index.ts, line 15
const ANTHROPIC_API_KEY = process.env.ANTHROPIC_API_KEY;
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.
