It compresses HTML, XML, CSS, JSON and JavaScript files both inline and as separate files using terser, cssminify2, json-minify and htmlcompressor. The gem only runs when `JEKYLL_ENV="production"` is set. 8 | 9 | ## Release Status (v0.2.1) 10 | 11 | **READY FOR RELEASE** - Security vulnerability patched: 12 | - ✅ **SECURITY FIX**: ReDoS vulnerability in preserve_patterns completely resolved 13 | - ✅ Comprehensive ReDoS protection with pattern validation and timeout guards 14 | - ✅ 100% backward compatibility maintained - all existing configs work unchanged 15 | - ✅ Extensive security test suite: 90/90 tests passing (74 original + 16 security) 16 | - ✅ Graceful degradation - dangerous patterns filtered with warnings, builds continue 17 | - ✅ Performance impact minimal - security checks complete in microseconds 18 | - ✅ Comprehensive security documentation added (SECURITY.md) 19 | 20 | ## Development Commands 21 | 22 | ### Local Development 23 | ```bash 24 | # Install dependencies 25 | bundle install 26 | 27 | # Build the gem 28 | gem build jekyll-minifier.gemspec 29 | 30 | # Run tests 31 | bundle exec rspec 32 | 33 | # Run all rake tasks (check available tasks first) 34 | bundle exec rake --tasks 35 | ``` 36 | 37 | ### Docker Development 38 | ```bash 39 | # Build Docker image 40 | docker compose build 41 | 42 | # Run tests in production environment (default) 43 | docker compose up jekyll-minifier 44 | 45 | # Run tests in development environment 46 | docker compose up test-dev 47 | 48 | # Build the gem 49 | docker compose up build 50 | 51 | # Get interactive shell for development 52 | docker compose run dev 53 | 54 | # Run specific commands 55 | docker compose run jekyll-minifier bundle exec rspec --format documentation 56 | ``` 57 | 58 | ## Architecture 59 | 60 | ### Core Structure 61 | - **Main module**: `Jekyll::Compressor` mixin that provides compression functionality 62 | - **Integration points**: Monkey patches Jekyll's `Document`, `Page`, and `StaticFile` classes to add compression during the write process 63 | - **File type detection**: Uses file extensions (`.js`, `.css`, `.json`, `.html`, `.xml`) to determine compression strategy 64 | 65 | ### Compression Strategy 66 | The gem handles different file types through dedicated methods: 67 | - `output_html()` - HTML/XML compression using HtmlCompressor 68 | - `output_js()` - JavaScript compression using Terser 69 | - `output_css()` - CSS compression using CSSminify2 70 | - `output_json()` - JSON minification using json-minify 71 | 72 | ### Key Design Patterns 73 | - **Mixin pattern**: `Jekyll::Compressor` module mixed into Jekyll core classes 74 | - **Strategy pattern**: Different compression methods based on file extension 75 | - **Configuration-driven**: Extensive YAML configuration options in `_config.yml` 76 | - **Environment-aware**: Only activates in production environment 77 | 78 | ### Configuration System 79 | All settings are under `jekyll-minifier` key in `_config.yml` with options like: 80 | - File exclusions via `exclude` (supports glob patterns) 81 | - HTML compression toggles (remove comments, spaces, etc.) 82 | - JavaScript/CSS/JSON compression toggles 83 | - Advanced options like preserve patterns and terser arguments 84 | 85 | ### Testing Framework 86 | - Uses RSpec for testing 87 | - Test fixtures in `spec/fixtures/` simulate a complete Jekyll site 88 | - Tests verify file generation and basic content validation 89 | - Mock Jekyll environment with production flag set 90 | 91 | ## File Organization 92 | - `lib/jekyll-minifier.rb` - Main compression logic and Jekyll integration 93 | - `lib/jekyll-minifier/version.rb` - Version constant 94 | - `spec/jekyll-minifier_spec.rb` - Test suite 95 | - `spec/spec_helper.rb` -

This document outlines the security measures implemented to protect against various attack vectors. 6 | 7 | ## ReDoS (Regular Expression Denial of Service) Protection 8 | 9 | ### Vulnerability Description 10 | 11 | Prior to version 0.2.1, Jekyll Minifier was vulnerable to ReDoS (Regular Expression Denial of Service) attacks through the `preserve_patterns` configuration option. Malicious regex patterns could cause the Jekyll build process to hang indefinitely, leading to denial of service. 12 | 13 | **Affected Code Location:** `lib/jekyll-minifier.rb` line 72 (pre-fix) 14 | 15 | ### Security Fix Implementation 16 | 17 | The vulnerability has been completely resolved with the following security measures: 18 | 19 | #### 1. Pattern Complexity Validation 20 | 21 | The gem now validates regex patterns before compilation: 22 | 23 | - **Length Limits**: Patterns longer than 1000 characters are rejected 24 | - **Nesting Depth**: Patterns with more than 10 nested parentheses are rejected 25 | - **Quantifier Limits**: Patterns with more than 20 quantifiers are rejected 26 | - **ReDoS Pattern Detection**: Common ReDoS vectors are automatically detected and blocked 27 | 28 | #### 2. Timeout Protection 29 | 30 | Regex compilation is protected by a timeout mechanism: 31 | 32 | - **1-second timeout** for pattern compilation 33 | - **Graceful failure** when timeout is exceeded 34 | - **Thread-safe implementation** to prevent resource leaks 35 | 36 | #### 3. Graceful Degradation 37 | 38 | When dangerous patterns are detected: 39 | 40 | - **Build continues successfully** without failing 41 | - **Warning messages** are logged for debugging 42 | - **Safe patterns** are still processed normally 43 | - **Zero impact** on existing functionality 44 | 45 | ### Backward Compatibility 46 | 47 | The security fix maintains **100% backward compatibility**: 48 | 49 | - All existing `preserve_patterns` configurations continue working unchanged 50 | - No new required configuration options 51 | - No breaking changes to the API 52 | - Same behavior for all valid patterns 53 | 54 | ### Protected Pattern Examples 55 | 56 | The following dangerous patterns are now automatically rejected: 57 | 58 | ```yaml 59 | # These patterns would cause ReDoS attacks (now blocked) 60 | jekyll-minifier: 61 | preserve_patterns: 62 | - "(a+)+" # Nested quantifiers 63 | - "(a*)*" # Nested quantifiers 64 | - "(a|a)*" # Alternation overlap 65 | - "(.*)*" # Exponential backtracking 66 | ``` 67 | 68 | ### Safe Pattern Examples 69 | 70 | These patterns continue to work normally: 71 | 72 | ```yaml 73 | # These patterns are safe and continue working 74 | jekyll-minifier: 75 | preserve_patterns: 76 | - ".*?" 77 | - "]*>.*?" 78 | - "]*>.*?" 79 | - "<%.*?%>" # ERB tags 80 | - "\{\{.*?\}\}" # Template variables 81 | ``` 82 | 83 | ## Security Best Practices 84 | 85 | ### 1. Pattern Design 86 | 87 | When creating `preserve_patterns`: 88 | 89 | - **Use non-greedy quantifiers** (`.*?` instead of `.*`) 90 | - **Anchor patterns** with specific boundaries 91 | - **Avoid nested quantifiers** like `(a+)+` or `(a*)*` 92 | - **Test patterns** with sample content before deployment 93 | - **Keep patterns simple** and specific 94 | 95 | ### 2. Configuration Security 96 | 97 | - **Validate user input** if accepting patterns from external sources 98 | - **Use allow-lists** instead of block-lists when possible 99 | - **Monitor build performance** for unusual delays 100 | - **Review patterns** during security audits 101 | 102 | ### 3. Development Security 103 | 104 | - **Run tests** after changing preserve patterns 105 | - **Monitor logs** for security warnings 106 | - **Update regularly** to receive security patches 107 | - **Use specific versions** in production (avoid floating versions) 108 | 109 | ## Vulnerability Disclosure 110 | 111 | If you discover a security vulnerability, please: 112 | 113 | 1. **Do not** create a public issue 114 | 2. **Email** the maintainers privately 115 | 3. **Provide** detailed reproduction steps 116 | 4. **Allow** reasonable time for response and patching 117 | 118 | ## Security Testing 119 | 120 | The gem includes comprehensive security tests: 121 | 122 | - **ReDoS attack simulation** with known dangerous patterns 123 | - **Timeout validation** to prevent hanging 124 | - **Pattern complexity testing** for edge cases 125 | - **Backward compatibility verification** 126 | - **Performance regression testing** 127 | 128 | Run security tests with: 129 | 130 | ```bash 131 | bundle exec rspec spec/security_redos_spec.rb 132 | ``` 133 | 134 | ## Security Timeline 135 | 136 | - **v0.2.0 and earlier**: Vulnerable to ReDoS attacks via preserve_patterns 137 | - **v0.2.1**: ReDoS vulnerability completely fixed with comprehensive protection 138 | - **Current**: All security measures active with full backward compatibility 139 | 140 | ## Compliance 141 | 142 | The security implementation follows: 143 | 144 | - **OWASP Top 10** guidelines for input validation 145 | - **CWE-1333** (ReDoS) prevention best practices 146 | - **Ruby security** standards for regex handling 147 | - **Secure development** lifecycle practices 148 | 149 | ## Security Contact 150 | 151 | For security-related questions or concerns, please contact the project maintainers through appropriate channels. 152 | 153 | --- 154 | 155 | **Note**: This security documentation is maintained alongside the codebase to ensure accuracy and completeness. -------------------------------------------------------------------------------- /FINAL_TEST_REPORT.md: -------------------------------------------------------------------------------- 1 | # Jekyll Minifier v0.2.0 - Final Test Coverage Report 2 | 3 | ## Executive Summary 4 | 5 | **TEST STATUS: EXCELLENT ✅** 6 | - **Total Tests**: 74/74 passing (100% success rate) 7 | - **Test Execution Time**: 1 minute 22.59 seconds 8 | - **Coverage Enhancement**: Added 33 new comprehensive tests 9 | - **Performance Baselines**: Established with ~1.06s average processing time 10 | 11 | ## Complete Test Suite Breakdown 12 | 13 | ### 1.

Enhanced CompressionConfig Class 55 | 56 | The `CompressionConfig` class now includes: 57 | 58 | #### Configuration Validation 59 | - Real-time validation during configuration loading 60 | - Type-specific validation per configuration key 61 | - Graceful fallback to safe defaults 62 | 63 | #### Compressor Arguments Validation 64 | - Terser/Uglifier argument safety checking 65 | - Known dangerous option detection 66 | - Legacy option filtering (`harmony` removal) 67 | - Nested configuration validation 68 | 69 | #### Backward Compatibility 70 | - All existing configurations continue to work 71 | - Invalid values fallback to safe defaults 72 | - No breaking changes to public API 73 | 74 | ### 3. Enhanced Compression Methods 75 | 76 | All compression methods now include: 77 | 78 | #### Pre-processing Validation 79 | - Content safety checking before compression 80 | - File path security validation 81 | - Size and encoding verification 82 | 83 | #### Error Handling 84 | - Graceful compression failure handling 85 | - Detailed error logging with file paths 86 | - Fallback to original content on errors 87 | 88 | #### Path-aware Processing 89 | - File-specific validation based on extension 90 | - Context-aware error messages 91 | - Secure file path handling 92 | 93 | ## Security Features 94 | 95 | ### 1. ReDoS Protection Integration 96 | - Works seamlessly with existing ReDoS protection 97 | - Layered security approach 98 | - Pattern validation at multiple levels 99 | 100 | ### 2. Resource Protection 101 | - Memory exhaustion prevention 102 | - CPU usage limits through timeouts 103 | - File size restrictions 104 | 105 | ### 3. Input Sanitization 106 | - Control character filtering 107 | - Encoding validation 108 | - Type coercion safety 109 | 110 | ### 4. Path Security 111 | - Directory traversal prevention 112 | - Null byte injection protection 113 | - Safe file handling 114 | 115 | ## Configuration Safety 116 | 117 | ### Validated Configuration Keys 118 | 119 | #### Boolean Options (with safe defaults) 120 | - All HTML compression options 121 | - File type compression toggles (`compress_css`, `compress_javascript`, `compress_json`) 122 | - CSS enhancement options 123 | - PHP preservation settings 124 | 125 | #### Array Options (with size limits) 126 | - `preserve_patterns` (max 100 patterns) 127 | - `exclude` (max 100 exclusions) 128 | 129 | #### Hash Options (with structure validation) 130 | - `terser_args` (max 20 options) 131 | - `uglifier_args` (legacy, with filtering) 132 | 133 | ### Example Safe Configurations 134 | 135 | ```yaml 136 | jekyll-minifier: 137 | # Boolean options - validated and converted 138 | compress_css: true 139 | compress_javascript: "true" # Converted to boolean 140 | remove_comments: 1 # Converted to boolean 141 | 142 | # Array options - validated and filtered 143 | preserve_patterns: 144 | - ".*?" 145 | - "]*>.*?" 146 | 147 | exclude: 148 | - "*.min.css" 149 | - "vendor/**" 150 | 151 | # Hash options - validated for safety 152 | terser_args: 153 | compress: true 154 | mangle: false 155 | ecma: 2015 156 | # Note: 'harmony' option automatically filtered 157 | ``` 158 | 159 | ## Error Handling and Logging 160 | 161 | ### Warning Categories 162 | 1. **Configuration Warnings**: Invalid config values with fallbacks 163 | 2. **Content Warnings**: Unsafe file content detection 164 | 3. **Security Warnings**: Path injection or other security issues 165 | 4. **Compression Warnings**: Processing errors with graceful recovery 166 | 167 | ### Example Warning Messages 168 | ``` 169 | Jekyll Minifier: Invalid boolean value for 'compress_css': invalid_value. Using default. 170 | Jekyll Minifier: File too large for safe processing: huge_file.css (60MB > 50MB) 171 | Jekyll Minifier: Unsafe file path detected: ../../../etc/passwd 172 | Jekyll Minifier: CSS compression failed for malformed.css: syntax error. Using original content. 173 | ``` 174 | 175 | ## Performance Impact 176 | 177 | ### Optimization Strategies 178 | - Validation occurs only during configuration loading 179 | - Content validation uses efficient algorithms 180 | -
