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

Rescanned at commit 917780c39259, unchanged since the check below.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED NETWORK_LOCALHOST SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/crabbox-setup/assets/cbx.sh, line 23 # secrets in env.allow are forwarded from your SHELL. We source .env so they're set.

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    skills/karaoke-captions/scripts/gen_ass.py, line 53 out = subprocess.check_output(cmd, stderr=subprocess.DEVNULL)

  • NETWORK_LOCALHOST Note

    Calls localhost only.

    skills/crabbox-setup/assets/setup.sh, line 70 if curl -sf "http://127.0.0.1:${APP_PORT}" >/dev/null 2>&1; then

  • SECRETS_ENV_READ Note

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

    skills/crabbox-setup/assets/setup.sh, line 49 # && sed -i "s|^MY_API_KEY=.*|MY_API_KEY=${MY_API_KEY}|" .env.local \

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.
