Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    lsp/client.go, line 78 cmd := exec.CommandContext(ctx, lc.command, lc.args...) // #nosec G204

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    lsp_spec_parser.py, line 31 response = requests.get(self.base_url, timeout=30)

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.
