During October 2025, Klane focused on security hardening for the element-hq/synapse repository, specifically improving OIDC session management. Klane implemented the Secure attribute on the oidc_session_no_samesite cookie, ensuring it is transmitted only over HTTPS and aligning its behavior with the existing oidc_session cookie. This backend development work, carried out in Python, addressed a key web security concern by reducing the risk of cookie leakage and session hijacking. The update demonstrated a solid understanding of web development and security best practices, with careful attention to cookie flag configuration and traceability, resulting in a targeted, high-impact feature enhancement.
