Alessandro Versari developed security testing infrastructure and documentation enhancements for Grafana credential disclosure scenarios across the google/security-testbeds and google/tsunami-security-scanner-plugins repositories. He built a reproducible testbed using Docker and Gradle to demonstrate and validate CVE-2022-26148, integrating a Tsunami plugin that detects exposed Zabbix credentials in Grafana deployments. His technical approach included refining advisory documentation in Markdown, clarifying vulnerability conditions, and improving test coverage with custom Java-based mock endpoints. Alessandro’s work focused on enabling robust, end-to-end vulnerability validation and clear security guidance, demonstrating depth in security research, code quality, and test infrastructure without requiring critical bug fixes during the period.
