Worked on the google/osv-scanner repository to enhance the accuracy of Go vulnerability detection by addressing a bug in package lookup logic. Focused on backend development using Go, the work involved modifying the vulnerability query process to correctly include major versions in Go package names. This adjustment aligned the lookup mechanism with Go PURL subpaths, ensuring that vulnerabilities were matched precisely, especially for modules with major version changes. The fix reduced false positives in CVE matching, thereby increasing the reliability of scan results for Go ecosystems. All changes were implemented with clear documentation and a dedicated commit to support maintainability and traceability.
