Jan 1, 2026January 2026 focused on security hardening in Netflix/zuul by implementing URI path normalization to prevent path traversal vulnerabilities. The change strips '.' and '..' segments from incoming URIs and includes tests to verify correct behavior, aligned with release #2042. This work was implemented with a single targeted commit: - 254b7f8cf4e8df89e048f4407d7c617d1dfaafdb (path normalization (#2042)). Impact: Reduces the risk of attackers accessing restricted resources via crafted paths at the gateway, improves routing reliability, and strengthens the overall security posture of the API gateway. The change introduces maintainable, test-covered code with clear rollback in case of regressions. Overall, this month delivered a concrete security remediation with minimal surface area and clear business value, while showcasing strong testing discipline and familiarity with the Zuul codebase.
