PROFILE

Filip Hanik

Worked on the cloudfoundry/uaa repository over three months, delivering three features focused on documentation, routing, and security. Updated the README to clarify Java 21 compatibility, improving onboarding and reducing ambiguity for Java developers. Enhanced backend routing by explicitly mapping trailing-slash URL variants and adding regression tests to ensure robust session management. Strengthened security by implementing access control for the rate-limiting status endpoint, restricting access to the default zone and enforcing token-based authentication. Utilized Java, Groovy, and the Spring Framework throughout, with a technical approach emphasizing maintainability, clear documentation, and comprehensive testing to align with enterprise requirements and best practices.

February 2026: Cloud Foundry UAA security and access-control improvement. Delivered rate-limiting status endpoint access control by constraining /RateLimitingStatus to the default zone and enforcing token-based authentication; updated integration tests to validate token-based access, ensuring only authorized users can retrieve rate-limiting status information. These changes reduce data exposure, strengthen security posture, and align with enterprise access-control requirements. The work demonstrates a strong focus on security, correct authorization flows, and maintainability of the rate-limiting visibility API.
