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

PERMISSION_SHELL_DECLARED OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    examples/bad/01-download-execute-cradle.ps1, line 22 Invoke-Expression $response.Content

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    benchmark/cases.json, line 1 {

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.
