NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    apps/desktop/src-tauri/src/issues.rs, line 2 //! Two stages: an FTS candidate fetch (messages mentioning error-ish tokens) keeps the scan

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    apps/desktop/src-tauri/src/issues.rs, line 2 //! Two stages: an FTS candidate fetch (messages mentioning error-ish tokens) keeps the scan

  • SECRETS_PATH_UNCONFIRMED Low

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

    apps/web/src/server/releases.ts, line 53 ...(process.env.GITHUB_TOKEN

  • SECRETS_ENV_READ Note

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

    apps/web/src/server/releases.ts, line 53 ...(process.env.GITHUB_TOKEN

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    pnpm-lock.yaml, line 1 lockfileVersion: '9.0'

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.
