Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit 27d7545b716d, unchanged since the check below.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
test-client/pay.mjs, line 50
const probe = await fetch(target); - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
test-client/pay.mjs, line 50
const probe = await fetch(target); - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
test-client/pay.mjs, line 10
const PRIVATE_KEY = process.env.PRIVATE_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.
