Grades are a hygiene check, not a security guarantee.

Pingfusi

Compatibility: Not stated.

Grade D

Two or more Medium findings, or a High finding. Only try it in a sandbox.

Graded by PlugVetRubric v2

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

Pattern found, check before installing

The checks matched a pattern that needs a closer look. It does not mean the code is harmful. Read the quoted lines below.

  • NETWORK_HOST_FROM_INPUT High

    host from input plus a credential path in operative code

NETWORK_HOST_FROM_INPUT 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.

    desktop-extension/server/index.mjs, line 63 res = await fetch(MCP_URL, {

  • SECRETS_PATH_CREDENTIAL Medium

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

    harness/installer-selftest.js, line 147 fs.writeFileSync(path.join(home, ".config", "pingfusi", "credentials.json"), JSON.stringify({ token: "

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    harness/agent-setup.js, line 169

    try { fs.rmSync(dest, { force: true }); } catch { /* leave what we can't delete */ }

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    package.json, line 36

  • Network

    Serious
