INSTALL_REMOTE_SCRIPT

Why this grade

  • INSTALL_REMOTE_SCRIPT Medium

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

    skills/agent-rules/references/examples/coding-agent-cli/scripts-AGENTS.md, line 315 curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y

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.

  • 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 was found in this repository, and it may apply to this entry.

  • Install and update

    Serious

    install fetches a script from the network. The docs document an installer that pipes a download into a shell.
