NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED 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/filter/network.rs, line 5 /// Filter curl/wget output.

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/config/env_file.rs, line 1 //! Optional `~/.config/ecotokens/.env`: `KEY=VALUE` lines exported into the

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    src/install.rs, line 644 completed = subprocess.run(

  • SECRETS_ENV_READ Note

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

    src/install.rs, line 619 ECOTOKENS_BIN = os.environ.get("ECOTOKENS_BIN", {binary:?})

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.
