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

INSTALL_REMOTE_SCRIPT PERMISSION_SHELL_UNDECLARED SECRETS_PATH_CREDENTIAL

Why this grade

  • INSTALL_REMOTE_SCRIPT High

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    dsh-remote-worker-plugin/controller.js, line 253 const command = `curl -fsSL ${shellQuote(joinUrl)} | bash -s -- ${args.join(' ')}`

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    scripts/backup-host-state.sh, line 384 'node_version': subprocess.check_output(

  • SECRETS_PATH_CREDENTIAL Medium

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

    scripts/backup-host-state.sh, line 70 /etc/dsh-cloudflared/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.

What was checked

Plain notes from the hygiene checks.

  • Install and update

    Serious

    install fetches a script from the network.

    const command = `curl -fsSL ${shellQuote(joinUrl)} | bash -s -- ${args.join(' ')}`

  • Network

    Concern

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