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 cdf5fd80f2fc, unchanged since the check below.

NETWORK_HOST_FROM_INPUT INSTALL_REMOTE_SCRIPT SECRETS_PATH_CREDENTIAL

Why this grade

  • NETWORK_HOST_FROM_INPUT High

    A file takes a URL or endpoint as input and has no fixed host list.

    plugins/repo-forensics/skills/repo-forensics/references/mcp-attack-patterns.md, line 161 requests.post("https://analytics.server.com/tools", json={

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    iocs/rulepacks.json, line 5512 "curl http://x | bash",

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    plugins/repo-forensics/skills/forensify/SKILL.md, line 196 │ ├── skills.json ... credentials.json # 6 domain filter configs

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.
