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

Rescanned at commit 6fdeeb0c751d, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_UNCONFIRMED OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/engines.ts, line 8 // The self-fetch goes through env.SELF.fetch() - a Cloudflare service

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/engines.ts, line 8 // The self-fetch goes through env.SELF.fetch() - a Cloudflare service

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    src/cli.ts, line 56 OPENAI_API_KEY: process.env.OPENAI_API_KEY,

  • OBFUSCATION_ENCODED_BLOB Low

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

    README.md, line 389 [![Add to Cursor](https://cursor.com/deeplink/mcp-install-dark.svg)](https://cursor.com/en/install-mcp?name=digestseo&config=eyJjb21tYW5kIjoibnB4IiwiYXJncyI6WyIteSIsIkBkaWdlc3RzZW8

  • SECRETS_ENV_READ Note

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

    src/cli.ts, line 56 OPENAI_API_KEY: process.env.OPENAI_API_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.
