CVE-2023-38546 is a vulnerability that affects the libcurl library, specifically the [curl_easy_duphandle]( function. This flaw allows an attacker to insert cookies into a running program using libcurl, under certain conditions. The vulnerability arises when a transfer with enabled cookies is duplicated, but the actual cookies are not cloned. Instead, the cloned handle stores the file name as `none`, inadvertently loading cookies from a file named `none` if it exists and is readable in the program's current directory. This vulnerability has a low base severity and requires no privileges or user interaction to exploit. It poses a potential risk to an organization's integrity, but not confidentiality or availability. Remediation for this vulnerability involves updating the libcurl library to fix the issue.
