Vulnerability Exploitability Exchange (VEX)

EXPERIMENTAL

This feature might change without preserving backwards compatibility.

Trivy supports filtering detected vulnerabilities using the Vulnerability Exploitability eXchange (VEX), a standardized format for sharing and exchanging information about vulnerabilities. By providing VEX during scanning, it is possible to filter vulnerabilities based on their status.

VEX Usage Methods

Trivy currently supports two methods for utilizing VEX:

1. VEX Repository
2. Local VEX Files
3. VEX Attestation

Enabling VEX

To enable VEX, use the --vex option. You can specify the method to use:

• To enable the VEX Repository: --vex repo
• To use a local VEX file: --vex /path/to/vex-document.json
• To enable VEX attestation discovery in OCI registry: --vex oci

$ trivy image ghcr.io/aquasecurity/trivy:0.52.0 --vex repo

You can enable these methods simultaneously. The order of specification determines the priority:

• --vex repo --vex /path/to/vex-document.json: VEX Repository has priority
• --vex /path/to/vex-document.json --vex repo: Local file has priority

For detailed information on each method, please refer to each page.
