In November 2024, Hotanya R. focused on security hardening for the Stirling-Tools/test-dont-use repository, addressing a self-XSS vulnerability in the merge interface. By leveraging JavaScript and front end development skills, Hotanya sanitized user-provided filenames and rendered them as plain text using the textContent property, effectively preventing script execution from malicious input. This targeted bug fix required minimal changes to the user interface, preserving the existing user experience while enhancing application security. The solution was code reviewed, passed QA validation with no regressions, and aligned with secure coding practices, demonstrating careful attention to both technical detail and workflow integrity.
