Worked on the Cognigy/Webchat repository to enhance application security through targeted dependency management using JavaScript. Focused on upgrading core libraries such as axios, dompurify, and lodash to address multiple high-risk vulnerabilities, the work involved remediating several CVEs without introducing feature regressions. The approach included validating all changes with automated tests and security scans to ensure stability and maintain feature parity. Additionally, the process was thoroughly documented to streamline future updates and reinforce security best practices. This initiative strengthened the baseline security posture of the application, reduced exposure to known vulnerabilities, and supported ongoing development and customer trust.
