Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    labs/12-deployment/scripts/container-smoke-test.sh, line 22 curl -fs "http://127.0.0.1:$PORT/ready" >/dev/null 2>&1 && break

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    labs/01-model-call/.env.example, line 1 # Copy to .env or export in your shell. Never commit real values.

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    scripts/sync-github-milestones.py, line 370 token = os.environ.get("GITHUB_TOKEN") or os.environ.get("GH_TOKEN")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command call was found in the code. This check does not read permissions an entry declares. A permission line to run shell commands and write or edit files was found in this repository, and it may apply to this entry.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.
