The triage process in the CVE Binary Tool enables users to customize vulnerability reports by adding contextual information such as mitigations or justifications for ignoring certain issues. This feature is especially useful for filtering out false positives or highlighting cases where a vulnerability is deemed non-exploitable based on a specific risk assessment.

While the CVE Binary Tool has offered basic triage support for some time, this GSoC project significantly extended its capabilities by integrating support for all four major VEX formats: CSAF, CycloneDX, OpenVEX, and SPDX. This was made possible through the integration of the lib4vex library, which provides robust parsing and generation of VEX documents across these different standards.

This talk will walk through the development journey, detailing the challenges faced while implementing VEX support and the key decisions that shaped the final solution.
