## Description

Hard-coded passwords are easily discovered through reverse engineering and cannot be changed without modifying the software. This creates a significant security risk as the password becomes public knowledge.

## Prevention

1 件の Shoulder 検出ルールに基づく Hardcoded Password の予防策。

### JavaScript

Load passwords from environment variables instead of hardcoding

## Warning Signs

- [HIGH] Hardcoded weak password detected: ...
This password is easily guessable and should never be used in production.

- [HIGH] hardcoded weak passwords in database connections and configuration

## Consequences

- 権限の取得
- 保護メカニズムの回避

## Mitigations

- パスワードは安全な構成ファイルまたは環境変数に保存する
- 安全な資格情報管理システムを使用する
- インストール時にランダムなパスワードを生成する

## Detection

- Total rules: 1
- Languages: javascript, typescript

## Rules by Language

### Javascript (1 rules)

- **Hardcoded Weak Password** [HIGH]: Detects hardcoded weak passwords in database connections and configuration.

Common weak passwords like "password", "admin", "root", "secret", etc. are
easily guessed and should never be hardcoded in source code.

This rule complements the high-entropy secrets detection by catching
simple, well-known weak passwords that entropy-based detection would miss.
  - Remediation: Move credentials to environment variables:

Before:
  password: 'password'

After:
  password: process.env.DB_PASSWORD

Then set DB_PASSWORD in your environment or .env file.

### Typescript (1 rules)

- **Hardcoded Weak Password** [HIGH]: Detects hardcoded weak passwords in database connections and configuration.

Common weak passwords like "password", "admin", "root", "secret", etc. are
easily guessed and should never be hardcoded in source code.

This rule complements the high-entropy secrets detection by catching
simple, well-known weak passwords that entropy-based detection would miss.
  - Remediation: Move credentials to environment variables:
