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.

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.
