Description ybuenos 2023-01-26 09:52:34 UTC 
Carefully crafted input can cause RFC2183 multipart boundary parsing in Rackto take an unexpected amount of time, possibly resulting in a denial of service attack vector. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted.
