Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
catalog/rules.json, line 213
"fetch(", - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
catalog/rules.json, line 213
"fetch(", - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.gitignore, line 31
.env - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.

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.

If a secret is loaded from a `.env` file, make sure that file is never reachable over HTTP and cannot be served by the web server as a static asset.
guides/sensitive-data-exposure/hard-coded-secrets.md, line 187
Treat `.env` files as sensitive deployment artifacts, not as public files that merely happen to live on the same host.
guides/sensitive-data-exposure/hard-coded-secrets.md, line 189
A stronger practice is to keep `.env` files or equivalent environment-variable bundles encrypted at rest. This reduces the chance that private keys and other credentials are expose
guides/sensitive-data-exposure/hard-coded-secrets.md, line 227
- Any `.env` file kept in the repository is encrypted at rest, and its decryption key is stored separately.
