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.
skills/plaid-link-setup/SKILL.md, line 67
fetch("/api/exchange-token", { - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.cursorrules, line 31
- Never hardcode `PLAID_CLIENT_ID`, `PLAID_SECRET`, or access tokens. Use environment variables or `.env` files. - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
mcp-server/src/tools/utils.ts, line 9
const secret = process.env.PLAID_SECRET;
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.
