During February 2026, this developer enhanced the prebid/prebid-server repository by delivering a focused feature in the ORTB blocking module. They implemented media type attribute validation, ensuring that banner, video, and audio attributes are strictly applied only to their relevant media types. This approach reduced the risk of cross-media attribute leakage and improved the reliability of ORTB request handling. Working primarily with Go, the developer applied backend development and API development skills, incorporating unit testing to verify correctness. The update strengthened data integrity within the blocking module, addressing a nuanced aspect of media type enforcement without introducing new bug fixes during the period.
