Fixed In Version: curl 7.85.0
Doc Type: If docs needed, set a value
Doc Text:
A vulnerability found in curl. This security flaw happens when curl is used to retrieve and parse cookies from an HTTP(S) server, where it accepts cookies using control codes (byte values below 32), and also when cookies that contain such control codes are later sent back to an HTTP(S) server, possibly causing the server to return a 400 response. This issue effectively allows a "sister site" to deny service to siblings and cause a denial of service attack.

Description Marian Rehak 2022-08-23 15:36:13 UTC 
When curl is used to retrieve and parse cookies from an HTTP(S) server, it accepts cookies using control codes (byte values below 32). When cookies that contain such control codes are later sent back to an HTTP(S) server, it might make the server return a 400 response. Effectively allowing a "sister site" to deny service to siblings.
