Fixed In Version: curl 7.83.1
Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in curl. The issue occurs because curl wrongly allows HTTP cookies to be set for Top Level Domains (TLDs) if the hostname is provided with a trailing dot. This flaw allows arbitrary sites to set cookies that get sent to a different and unrelated site or domain by a malicious actor.

Description Marian Rehak 2022-05-05 15:03:17 UTC 
libcurl wrongly allows HTTP cookies to be set for Top Level Domains (TLDs) if the host name is provided with a trailing dot. This can allow arbitrary sites to set cookies that then would get sent to a different and unrelated site or domain.
