Worked on the langflow-ai/langflow repository to address a security-critical issue involving session termination. Focused on backend development using Python, the work involved refining the logout endpoint to ensure cookies were deleted with parameters precisely matching those set during login. This approach improved session security by preventing lingering authenticated sessions, particularly in shared or mixed HTTP/HTTPS environments. The solution aligned logout and login cookie handling, reducing the risk of stale sessions and enhancing overall security posture. Collaborated with other contributors and automated tools, applying security best practices throughout the process to deliver a robust fix for a high-priority authentication bug.
