Rescanned at commit 04c659934c4c, unchanged since the check below.

NETWORK_HOST_FROM_INPUT INSTALL_LIFECYCLE_HOOK SECRETS_PATH_CREDENTIAL

Why this grade

  • NETWORK_HOST_FROM_INPUT High

    A file takes a URL or endpoint as input and has no fixed host list.

    deploy/deploy-vps.sh, line 8 p -d --build --remove-orphans; sleep 3; curl -fsS http://127.0.0.1:8787/healthz && ec

  • INSTALL_LIFECYCLE_HOOK Medium

    A package install hook (preinstall, install, postinstall or prepare) runs a script.

    package.json, line 15 prepare

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    CLAUDE.md, line 19 npm run auth -- --client-secret ./client_secret.json # 一次性 OAuth 授权,写入 ~/.config/google-seo-mcp/credentials.json

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.
