v0.1.14

This release fixes critical false positives in both the SQL Injection and DoS checkers, improving accuracy and reducing noise.

🐛 Bug Fixes & False-Positive Reductions

• SQL Injection False-Positive Fix: String interpolation is now only flagged if it occurs in the first string argument (the SQL template string). Safe string interpolations inside query bind arguments (e.g. where("street_number ILIKE ?", "#{value}%")) are no longer flagged.
• Pagy Pagination Support: The DoS checker now automatically detects queries wrapped inside pagy(...) or pagy_countless(...) pagination helpers (both single-line and multi-line formats) and avoids marking them as unbounded queries.

Special thanks to @Z2Flow for reporting these false positives!

v0.1.13

This release introduces ignore file support (.guarddogignore), fixes a path resolution bug, and makes configuration initialization more seamless when integrating with Rails.

🚀 New Features & Enhancements

• Ignore File Support (.guarddogignore): You can now add a .guarddogignore file in your Rails project root to silence specific checkers or exclude entire files/directories completely.
  • Exclude a file/directory completely:

    db/seeds.rb
    vendor/
    

  • Exclude specific checkers for specific files/directories:

    db/seeds.rb: secrets
    app/controllers/admin/*: sql_injection, csrf
    

• Automatic Rails Config Integration: Rails::Guarddog::Scanner now automatically resolves and falls back to Rails.application.config.guarddog configuration if no configuration object is explicitly passed to its initializer.

🐛 Bug Fixes

• Strict Path Matching: Refactored BaseChecker directory exclusion/ignores to use relative paths rather than absolute paths. This fixes a bug where absolute path matches in parent directories (such as temp directories containing the word test) caused unexpected check suppressions.

Rails GuardDog v0.1.12

This release introduces significant enhancements to false-positive protections across checkers, directory-based check suppression, and a more flexible configuration API.

🚀 New Features & Enhancements

• Per-Directory Check Suppression (ignored_checks): You can now silence specific checkers within specific directories (e.g., ignoring secrets alerts inside test directories) while leaving all other security checks active. By default, secrets checks are now ignored inside spec/ and test/ directories.

  Rails.application.config.guarddog.ignored_checks = {
    "spec"     => %w[secrets],          # skip secrets checker in spec/
    "test"     => %w[secrets],          # skip secrets checker in test/
    "fixtures" => %w[secrets idor]      # skip secrets & idor checkers in fixtures/
  }

• Easy Checker Exclusion (disabled_checkers): A new configuration option allows you to keep all checkers active except a few, making configuration easier to maintain.

  Rails.application.config.guarddog.disabled_checkers = %w[dos rate_limit]

🐛 Bug Fixes & False-Positive Reductions

• Secrets Checker false-positive elimination:
  • Added word boundaries (\b) to regex patterns to prevent substrings (like no_token: or reset_password_instructions:) from triggering alerts.
  • Required secret values to be space-free ([^\s'"]{6,}) to prevent English translation sentences in locale files from being flagged as hardcoded secrets.
  • Automatically skip translation locale files (config/locales/).
• DoS Checker false-positive elimination:
  • Unbounded database query alerts are now only triggered when .all is called on a PascalCase constant (e.g. User.all or Post.where(...).all). Lowercase receivers (like current_user.permissions.all) and enumerable predicate methods (like .all?) are now ignored.
  • Added Smart Multiline .limit() Detection: The checker now looks ahead up to 3 lines to detect chained .limit() calls on subsequent lines or separate variable assignments.

    # The following patterns are now correctly identified as safe:
    things = Thing.all
                  .limit(100)
    
    things = Thing.all
    things = things.limit(100)
