vulnx

Modern CLI for exploring vulnerability data with powerful search, filtering, and analysis capabilities

🚀 Migration Notice

vulnx is the next generation of cvemap - we recommend upgrading to vulnx for the latest features and improvements.

⚠️ Important: cvemap uses an older API version that will be discontinued on August 1, 2025.

Quick Start

# 1. Get vulnx
go install github.com/projectdiscovery/cvemap/cmd/vulnx@latest
# 2. Explore commands
vulnx --help
vulnx search --help
# 3. Start exploring vulnerabilities (no API key required)
vulnx filters # See all available search fields
vulnx search apache # Basic search (subject to rate limits)
# 4. Set up your API key (recommended to avoid rate limits)
vulnx auth # Get free API key at https://cloud.projectdiscovery.io
# 5. Enhanced exploration with higher limits
vulnx search apache # No rate limits
vulnx id CVE-2021-44228 # Faster responses

What vulnx Does

Search vulnerabilities with precision:

vulnx search "severity:critical && is_remote:true"
vulnx search "apache || nginx" --limit 20
vulnx search "cvss_score:>8.0 && cve_created_at:2024"

Get detailed vulnerability info:

vulnx id CVE-2021-44228
vulnx id CVE-2024-1234 --json

Analyze vulnerability patterns:

vulnx analyze --fields severity
vulnx analyze --fields affected_products.vendor

Core Commands

Command	Purpose	Example
`search`	Find vulnerabilities with advanced filters	`vulnx search "apache && severity:high"`
`id`	Get details for specific CVE	`vulnx id CVE-2021-44228`
`filters`	List all available search fields and filters	`vulnx filters`
`analyze`	Aggregate data by fields	`vulnx analyze -f severity`

Essential Options

Output formats:

vulnx search "apache" --json # Machine-readable JSON
vulnx search "apache" --output results.json # Save to file
vulnx search "apache" --silent # Quiet output

Search control:

vulnx search "apache" --limit 50 # Get 50 results
vulnx search "apache" --sort-desc cvss_score # Sort by CVSS score
vulnx search "apache" --fields cve_id,severity # Specific fields only

Advanced search:

vulnx search --term-facets severity=5,tags=10 "apache"
vulnx search --range-facets numeric:cvss_score:high:8:10 "remote"
vulnx search --highlight "apache" # Enable search highlighting
vulnx search --facet-size 20 "nginx" # More facet buckets
vulnx search --detailed "xss" # Detailed output like 'id' command

Discovering Available Fields

Explore what you can search on:

vulnx filters # Show all available search fields
vulnx filters --json # Machine-readable field list
vulnx filters --output fields.json # Save field info to file

The filters command shows detailed information about all searchable fields including:

Field names and data types
Descriptions and examples
Whether fields support sorting and faceting
Available enum values for specific fields
Search analyzer types

Example output:

Field: severity
Data Type: string
Description: Vulnerability severity level (e.g., critical, high, medium, low, info)
Can Sort: Yes
Facet Possible: Yes
Search Analyzer: keyword-lower
Examples: severity:critical, severity:high
Enum Values: critical, high, medium, low, info, unknown
Total: 69 filters available

Use this command to discover new search possibilities and understand field syntax before building complex queries.

Common Search Patterns

Find high-risk vulnerabilities:

vulnx search "severity:critical && is_remote:true && is_kev:true"
vulnx search "cvss_score:>8.0 && cve_created_at:>=2024" # High CVSS from 2024
vulnx search "is_kev:true && age_in_days:<90" # Recent KEV exploits

Search by technology:

vulnx search "apache" # Apache vulnerabilities
vulnx search "apache || nginx" # Multiple technologies
vulnx search "affected_products.vendor:microsoft" # By vendor

Filter by severity and scores:

vulnx search "severity:high" # High severity
vulnx search "cvss_score:>7.0" # CVSS score above 7
vulnx search "epss_score:>0.8" # High EPSS score

Time-based searches:

vulnx search "cve_created_at:>=2024" # Published in 2024 or later
vulnx search "cve_created_at:>=2024年01月01日 && cve_created_at:<2024年07月01日" # First half of 2024
vulnx search "age_in_days:<30" # Recent vulnerabilities (last 30 days)

Find exploitable vulnerabilities:

vulnx search "is_poc:true" # Has proof of concept
vulnx search "is_kev:true" # Known exploited vulns
vulnx search "is_template:true" # Has Nuclei templates
vulnx search --detailed "log4j" # Detailed analysis of specific vuln

Query Syntax

Basic searches:

vulnx search "apache" # Simple term
vulnx search "remote code execution" # Phrase search
vulnx search "severity:critical" # Field search

Boolean logic:

vulnx search "apache && nginx" # Both terms
vulnx search "apache || nginx" # Either term
vulnx search "apache NOT tomcat" # Exclude term
vulnx search "(apache || nginx) && severity:high" # Grouped

Ranges and wildcards:

vulnx search "cvss_score:>8.0" # Greater than
vulnx search "cvss_score:<9.0" # Less than
vulnx search "cve_created_at:>=2024年01月01日" # Date comparison
vulnx search "age_in_days:<30" # Recent vulnerabilities
vulnx search "apache*" # Wildcard

Date Queries

Important: Date fields require comparison operators (>=, >, <, <=).

Single date comparisons:

vulnx search "cve_created_at:>=2024" # CVEs from 2024 onward
vulnx search "cve_created_at:<2024" # CVEs before 2024
vulnx search "cve_created_at:>2024年06月01日" # CVEs after June 1, 2024

Date ranges:

# CVEs from January 2024 only
vulnx search "cve_created_at:>=2024年01月01日 && cve_created_at:<2024年02月01日"
# High CVSS CVEs from 2024
vulnx search "cvss_score:>8.0 && cve_created_at:>=2024"
# Recent vulnerabilities (age-based)
vulnx search "age_in_days:<30" # Last 30 days
vulnx search "age_in_days:>365" # Older than 1 year

Supported formats:

2024 (year)
2024-01 (year-month)
2024年01月15日 (full date)

Configuration

Authentication (Optional)

vulnx works without an API key, but authentication provides significant benefits:

⚠️ Without API key:

Limited to 10 requests per minutes
Subject to strict rate limits
May encounter "429 Too Many Requests" errors

✅ With API key:

Much higher rate limits
Access to all the filters

Set up authentication:

vulnx auth # Interactive setup
vulnx auth --api-key YOUR_API_KEY # Non-interactive (automation)
vulnx auth --test # Test current API key
export PDCP_API_KEY="your-key-here" # Environment variable

Authentication modes:

Interactive: vulnx auth - Guided setup with prompts
Non-interactive: vulnx auth --api-key KEY - Perfect for automation/CI/CD
Test only: vulnx auth --test - Validate current configuration

Version management:

vulnx version # Show version and check for updates
vulnx version --disable-update-check # Show version without update check
vulnx update # Update to latest version
vulnx --update # Alternative update command

Global options:

vulnx --json search "apache" # JSON output
vulnx --silent search "apache" # No banner
vulnx --timeout 60s search "apache" # Custom timeout
vulnx --disable-update-check search "apache" # Disable automatic update checks

Troubleshooting

Rate limit issues:

Rate limit exceeded! API key required for higher limits.
→ Run: vulnx auth to configure API key and get higher limits

Automation/CI/CD setup:

# Docker containers
vulnx auth --api-key "$SECRET_API_KEY"
# CI/CD pipelines
vulnx auth --api-key "${PDCP_API_KEY}"
# Kubernetes init containers
vulnx auth --api-key "$(cat /secrets/api-key)"
# Test authentication in scripts
vulnx auth --test && echo "Auth OK" || echo "Auth failed"

Rate limit suggestions:

Configure API key with 'vulnx auth' to avoid rate limits
→ This appears when no API key is configured. To remove:
 1. Set up API key: vulnx auth
 2. Or use --silent flag to suppress informational messages

No results:

vulnx search "is_kev:true" --limit 1 # Test with known results
vulnx healthcheck # Check connectivity

Large result sets:

vulnx search "apache" --limit 100 # Increase limit
vulnx search "apache" --offset 100 # Pagination
vulnx search --fields cve_id,severity "apache" # Fewer fields

Connection issues:

vulnx --timeout 60s search "apache" # Increase timeout
vulnx --proxy http://localhost:8080 search "apache" # Use proxy
vulnx --debug search "apache" # Debug mode

Getting Help

Help commands (no API key required):

vulnx --help # All commands overview
vulnx search --help # Search command help
vulnx id --help # ID command help
vulnx filters --help # Filters command help
vulnx analyze --help # Analyze command help
vulnx version # Version info with update check
vulnx version --disable-update-check # Version info without update check

Data exploration (subject to rate limits without API key):

vulnx filters # Show all searchable fields
vulnx search help # Detailed search fields
vulnx analyze help # Available analyze fields

⚠️ Note All commands work without an API key, but are subject to rate limits. Configure an API key with vulnx auth for higher limits and better performance.

Tips

Start immediately: vulnx works without an API key - just run vulnx search apache
Avoid rate limits: Configure API key with vulnx auth for heavy usage
Stay updated: vulnx automatically checks for updates; use --disable-update-check to disable
Use vulnx filters to discover all available search fields and their syntax
Start with broad searches, then narrow down with filters
Use --json for scripting and automation
Combine multiple filters for precise results
Use analyze to understand data patterns
Save frequently used queries as shell aliases
