Berkay Kirali developed a security-focused YAML template for the projectdiscovery/nuclei-templates repository, targeting the critical XML External Entity (XXE) vulnerability CVE-2025-66516 in Apache Tika. His work centered on YAML configuration and security testing, providing a template that outlines the vulnerability’s impact, remediation steps, and example payloads to streamline vulnerability assessment. By standardizing the XXE testing workflow, Berkay improved automation readiness for future templates and enhanced the project’s ability to validate and remediate similar issues. Although no bugs were fixed during this period, his contribution demonstrated depth in vulnerability assessment and practical application of YAML for security automation.
