Go Security Vulnerability Skill

Use Go tooling to identify, assess, and fix security vulnerabilities in Go modules. This skill helps detect and remediate vulnerabilities while maintaining application functionality.

Vulnerability Detection

Scan for vulnerabilities in your Go project:

bash

go install golang.org/x/vuln/cmd/govulncheck@latest
govulncheck ./...

Check specific modules for known vulnerabilities:

bash

govulncheck -show verbose ./...

Assessment Process

Identify Affected Packages: Determine which dependencies contain vulnerabilities
Check Severity: Review the CVE details and potential impact
Verify Usage: Confirm if the vulnerable functions are actually used in your code
Plan Remediation: Choose the appropriate fix strategy

Common Fix Strategies

Direct Dependency Update

Update vulnerable packages to secure versions:

bash

go get -u vulnerable/package@latest
go mod tidy

Transitive Dependency Handling

For vulnerabilities in transitive dependencies:

bash

go mod why vulnerable/package  # Understand why it's included
go mod edit -replace vulnerable/package=newer-version  # Replace if needed
go mod tidy

Removal Strategy

If a dependency is unused or can be replaced:

Remove direct imports of the vulnerable code
Run go mod tidy to clean up unused dependencies
Verify application functionality remains intact

Verification Steps

After applying fixes:

bash

# Verify no vulnerabilities remain
govulncheck ./...

# Ensure application still builds
go build ./...

# Run tests to verify functionality
go test ./...

Common Vulnerabilities

JWT Libraries

Issue: github.com/golang-jwt/jwt GO-2025-3553 (excessive memory allocation)
Fix: Update to newer version or switch to golang.org/x/oauth2 alternatives

Standard Library Updates

Keep Go version updated for security patches
Run go vuln to check for stdlib vulnerabilities

Best Practices

Regularly scan dependencies with govulncheck
Keep dependencies updated with go get -u
Use go mod tidy to remove unused dependencies
Test thoroughly after vulnerability fixes
Monitor for new vulnerabilities with automated tools

Installation

Terminal bash


openclaw install go-security-vulnerability

💻Code Examples

govulncheck -show verbose ./...

govulncheck--show-verbose-.txt

## Assessment Process

1. **Identify Affected Packages**: Determine which dependencies contain vulnerabilities
2. **Check Severity**: Review the CVE details and potential impact
3. **Verify Usage**: Confirm if the vulnerable functions are actually used in your code
4. **Plan Remediation**: Choose the appropriate fix strategy

## Common Fix Strategies

### Direct Dependency Update
Update vulnerable packages to secure versions:

go mod tidy

go-mod-tidy.txt

### Transitive Dependency Handling
For vulnerabilities in transitive dependencies:

go mod tidy

go-mod-tidy.txt

### Removal Strategy
If a dependency is unused or can be replaced:

1. Remove direct imports of the vulnerable code
2. Run `go mod tidy` to clean up unused dependencies
3. Verify application functionality remains intact

## Verification Steps

After applying fixes:

example.sh

go mod why vulnerable/package  # Understand why it's included
go mod edit -replace vulnerable/package=newer-version  # Replace if needed
go mod tidy

example.sh

# Verify no vulnerabilities remain
govulncheck ./...

# Ensure application still builds
go build ./...

# Run tests to verify functionality
go test ./...
