Grades are a hygiene check, not a security guarantee.

nestrs

NestJS-like API framework for Rust built on Axum and Tower.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    examples/lab/src/bin/lab3_files.rs, line 46 /// Multipart upload: curl -F file=@somefile

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    nestrs/src/config.rs, line 30 /// Load typed config from environment variables (optionally `.env` / `.env.<env>` in non-production),

  • PERMISSION_SHELL_DECLARED Note

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

    .github/workflows/ci.yml, line 29 out = subprocess.check_output(["git", "ls-files", "-z"])

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    Cargo.lock, line 1 # This file is automatically @generated by Cargo.

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    Cargo.lock, line 1 # This file is automatically @generated by Cargo.

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    examples/lab/src/bin/lab3_files.rs, line 46

    /// Multipart upload: curl -F file=@somefile

    nestrs-cli/src/repl.rs, line 21

    //! be parsed as a curl flag. Requires `curl` on `$PATH`.

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_PATH_DOTENV

    nestrs/src/config.rs, line 30

    /// Load typed config from environment variables (optionally `.env` / `.env.<env>` in non-production),

    nestrs/src/config.rs, line 39

    let _ = dotenvy::from_filename(format!(".env.{env}"));

    nestrs/src/config.rs, line 74

    /// cascade therefore has the *lowest* precedence: `.env.local` wins over

    Show more

    nestrs/src/config.rs, line 75

    /// `.env`). Missing files are skipped silently, matching `dotenvy::dotenv`.

    nestrs/src/config.rs, line 89

    /// Build the env overlay: `.env` → `.env.{env}` → `.env.{env}.local`

    nestrs/src/config.rs, line 103

    merge_dotenv_file(&mut map, &dir.join(".env"));

    nestrs/src/config.rs, line 104

    merge_dotenv_file(&mut map, &dir.join(format!(".env.{env}")));

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Note

    a file was over the read cap and was not fully read. the file cap was reached before every file was read.
