Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit 427db42c92a8, unchanged since the check below.
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.
third-party/addyosmani/skills/security-and-hardening/references/hardening-patterns.md, line 127
await fetch(req.body.webhookUrl); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
third-party/addyosmani/skills/ci-cd-and-automation/SKILL.md, line 274
.env.example → Committed (template for developers) - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
third-party/addyosmani/skills/security-and-hardening/references/hardening-patterns.md, line 36
secret: process.env.SESSION_SECRET, // From environment, not code
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.
