Grade C

One Medium finding. Read the report before installing.

Graded by PlugVetRubric v2

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

SECRETS_PATH_CREDENTIAL

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

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

    engine/src/workspace/ignore.ts, line 19 "id_rsa",

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    engine/src/auth/store.ts, line 266

    fs.rmSync(file, { force: true });

    engine/src/bridge/runtime.ts, line 37

    engine/src/browser/supervisor.ts, line 249

    try { fs.unlinkSync(runtimeFile()); } catch { /* no runtime file */ }

  • Install and update

    Pass

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

  • Network

    Concern
