This commit adds a comprehensive example demonstrating the govulncheck action's capabilities, along with several enhancements to improve the user experience.
## Changes
### Example Setup
- Added example/main.go that uses golang.org/x/net v0.0.0-20220906165146-f3363e06e74c (vulnerable version)
- Example intentionally calls html.Parse to trigger vulnerability detection
- Demonstrates how the action creates annotations on vulnerable code
### Enhanced Annotations
- Fixed file path handling when running in subdirectories (e.g., './example')
- Added rich context to annotations including:
- Vulnerability summaries and CVE numbers
- Direct links to Go vulnerability database (pkg.go.dev/vuln)
- Fixed version information
- Clear indication of which function is vulnerable (e.g., "html.Parse" not "main")
- Sorted vulnerabilities by OSV ID for consistent display
### Suggested Fixes
- When vulnerable code is actually called, creates notice annotations on go.mod
- Shows current vs suggested dependency versions
- Lists which specific vulnerabilities have active call sites
- Provides actionable upgrade recommendations
### Workflow Summary
- Added comprehensive workflow summary using GitHub Actions summary API
- Displays vulnerabilities in formatted tables by module
- Shows vulnerable code locations organized by file
- Includes links to Go vulnerability database entries
- Provides clear recommendations for fixing vulnerabilities
### Bug Fixes
- Fixed JSON parsing to handle both JSON lines and multi-line JSON formats
- Fixed annotation file paths to be relative to repository root
- Improved vulnerability function name extraction from trace data
- Enhanced OSV detail parsing and storage
## Testing
The example workflow demonstrates all features by intentionally using a vulnerable dependency. When run, it will:
1. Detect vulnerabilities in golang.org/x/net
2. Create warning annotations on go.mod and main.go
3. Suggest specific version updates
4. Generate a detailed workflow summary
This provides a complete demonstration of the action's vulnerability detection and reporting capabilities.
This action runs govulncheck on Go projects and creates GitHub annotations
for vulnerabilities found in dependencies and code paths.
Features:
- Automated vulnerability scanning with govulncheck
- Smart annotations on go.mod for vulnerable dependencies
- Annotations on source code lines that call vulnerable functions
- Configurable working directory
- Output variables for vulnerability detection
The implementation includes:
- Modular architecture with separate concerns (execution, parsing, annotation)
- Comprehensive test suite with 100% function coverage
- Example vulnerable Go module for demonstration
- GitHub workflow example
- Full documentation
