Grade D

Two or more Medium findings, or a High finding. Only try it in a sandbox.

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

Rescanned at commit d8b774b0959b, unchanged since the check below.

PERMISSION_SHELL_UNDECLARED INSTALL_LIFECYCLE_HOOK

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

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

    cmd/codehelper/update.go, line 145 build := exec.Command("go", args...)

  • INSTALL_LIFECYCLE_HOOK Medium

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

    README.md, line 32 curl -fsSL https://raw.githubusercontent.com/VeyrForge/codehelper/main/scripts/install.sh | sh

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

    Concern

    requests shell access. No manifest field names shell or command execution.

    cmd := exec.Command("git", "-C", repoRoot, "diff", baseRef)

  • Install and update

    Concern

    runs a script at install time. README documents an installer that pipes a download into a shell. The docs document an installer that pipes a download into a shell.

    Concern
