const request = https.request(url, { method: "HEAD" }, (response) => { - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.

const request = https.request(url, { method: "HEAD" }, (response) => { - SECRETS_PATH_DOTENV Low

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.
