Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
src/auth.ts, line 127
fs.unlinkSync(SESSION_FILE); - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
browser-extension/src/background.ts, line 6
const res = await fetch("http://localhost:4318/health", { signal: AbortSignal.timeout(2000) }); - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
browser-extension/src/background.ts, line 6
const res = await fetch("http://localhost:4318/health", { signal: AbortSignal.timeout(2000) }); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
CLAUDE.md, line 19
├── sandbox.ts → .env sandbox with deterministic fakes (HMAC-SHA256) - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
api/webhook.js, line 9
const privKeyBase64 = process.env.KEYBLIND_SIGNING_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.
