Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from improper validation in the Range header processing. The commit diff explicitly modifies get_byte_ranges in lib/rack/utils.rb to add a critical size check. While Rack::File and Rack::Utils.byte_ranges are mentioned as entry points, the root cause is the unpatched get_byte_ranges method. The advisory confirms this by stating applications using these components are vulnerable, and the patch directly targets get_byte_ranges.
