PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/mastra/tools/data-file-manager.ts, line 126 await fs.unlink(fullPath);

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    src/mastra/tools/weather-tool.ts, line 67 const geocodingResponse = await fetch(geocodingUrl);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .github/workflows/gemini-invoke.yml, line 143 - **Prevent Leaks**: Never repeat or "post back" the full contents of a file in a comment, especially configuration files (`.json`, `.yml`, `.toml`, `.env`). Instead, describe the

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    package-lock.json, line 1 {

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/mastra/index.ts, line 71 publicKey: process.env.LANGFUSE_PUBLIC_KEY,

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.
