Rescanned at commit 89a07fe8143e, unchanged since the check below.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_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.
api/checkout.ts, line 52
const r = await fetch("https://api.stripe.com/v1/checkout/sessions", { - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
api/checkout.ts, line 52
const r = await fetch("https://api.stripe.com/v1/checkout/sessions", { - SECRETS_PATH_DOTENV Low
Mentions a .env file.
src/voice/mcp.ts, line 89
* plain `.env` - crixin voice doesn't care. - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
api/checkout.ts, line 26
const secret = process.env["STRIPE_SECRET_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.
