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

Rescanned at commit df6fe27f0a3c, 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.

    integrations/langchain/sign_cli_tools.py, line 42 self.proc = subprocess.Popen(

  • INSTALL_LIFECYCLE_HOOK Medium

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

    package.json, line 80 postinstall

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.
