Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit 96537d195343, unchanged since the check below.

SECRETS_PATH_DOTENV NETWORK_LOCALHOST

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/server.ts, line 114 // a prompt-injection exfiltration vector (.env, keys) - no allowlist, no tool.

  • NETWORK_LOCALHOST Note

    Calls localhost only.

    src/index.ts, line 42 const res = await fetch(`http://127.0.0.1:${port}/healthz`, { signal: AbortSignal.timeout(1500) });

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.

    SECRETS_PATH_DOTENV

    src/server.ts, line 114

    // a prompt-injection exfiltration vector (.env, keys) - no allowlist, no tool.

    CHANGELOG.md, line 157

    prompt-injection exfiltration vector (`.env`, keys) - removed rather than allowlisted.

    - There is deliberately **no file-sharing tool**: an arbitrary-path "share this file" tool is a prompt-injection exfiltration vector (`.env`, keys) - a hijacked agent could publish

    README.zh-TW.md, line 229

    - 刻意**沒有檔案分享工具**：可傳任意路徑的「分享這個檔案」工具是 prompt injection 的洩密面（`.env`、金鑰） - - 被劫持的 agent 可以直接把機敏檔發佈出去。與其做 allowlist 不如整個拿掉。
