Frank van Hoof enhanced the security posture of the homarr-labs/homarr repository by implementing a hardened Content Security Policy and refining href protocol validation. Using JavaScript, TypeScript, and Next.js, he introduced stricter controls to disallow the javascript: protocol in links while supporting custom protocols, thereby reducing the risk of cross-site scripting attacks. His work focused on tightening script source restrictions and improving validation logic, which helped ensure safer embedding of third-party content without disrupting user experience. Over the course of one month, Frank’s targeted feature work addressed core security concerns, contributing to compliance with best practices and a more robust application baseline.
