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

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST PERMISSION_SHELL_DECLARED OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/download-stats.sh, line 14 npm_total=$(curl -sf --max-time 10 "https://api.npmjs.org/downloads/point/2000-01-01:2030-01-01/${NPM_PKG}" \

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/download-stats.sh, line 14 npm_total=$(curl -sf --max-time 10 "https://api.npmjs.org/downloads/point/2000-01-01:2030-01-01/${NPM_PKG}" \

  • PERMISSION_SHELL_DECLARED Note

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

    frontend_http.go, line 183 cmd := exec.Command(f.serverCmd, f.serverArgs...)

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    gcf-proxy, 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.
