In November 2025, Ibenchhida Ben worked on the apache/spark repository, focusing on enhancing the security of the Spark UI’s History Page. Using JavaScript and front end development skills, Ibenchhida implemented XSS protection by escaping application names to prevent cross-site scripting vulnerabilities. The solution was carefully integrated with existing tests and manually validated to ensure no user-facing changes or regressions in the dashboard. This targeted bug fix addressed a specific security risk while maintaining UI stability and performance. The work demonstrated a methodical approach to secure coding practices, emphasizing minimal impact on usability and preserving the simplicity of the interface.
