Severity Low
Score 3.7/10


When curl versions from 4.9 through 7.84.0 used to retrieve and parse cookies from a HTTP(S) server, it accepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a "sister site" to deny service to all siblings.
