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

Rescanned at commit 6b927de6aca9, unchanged since the check below.

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.

    cli/src/commands/doctor.js, line 46 const res = await fetch('https://registry.npmjs.org/remnus/latest', { signal: controller.signal });

  • SECRETS_PATH_CREDENTIAL Medium

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

    cli/src/commands/doctor.js, line 213 // is committed and `credentials.json` is not, so everyone after the first person

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

    cli/src/lib/map.js, line 96

    try { fs.unlinkSync(tmp); } catch { /* already gone */ }

    mcpb/server/index.js, line 150

    try { fs.unlinkSync(LOCK_PATH); } catch { /* raced with the owner's own cleanup */ }

    mcpb/server/index.js, line 160

    try { fs.unlinkSync(LOCK_PATH); } catch { /* already gone */ }

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Serious

    accepts a host from input, with no fixed list in this file.

  • Secrets

    Concern

    reads a credential or environment file.
