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

Rescanned at commit 06192ff552f0, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/resolver.js, line 185 fs.rmSync(cloneRoot, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    src/analyzers/postinstall.js, line 51 message: "curl/wget piped to shell in lifecycle script",

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/constants.js, line 47 ".env",

  • OBFUSCATION_ENCODED_BLOB Low

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

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.
