CVE-2023-38546 This flaw allows an attacker to insert cookies at will into a running program using libcurl if the specific series of conditions are met. libcurl performs transfers. In its API an application creates “easy handles” that are the individual handles for single transfers. libcurl provides a function call that duplicates en easy handle called [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies enabled when the handle is duplicated the cookie-enable state is also cloned – but without cloning the actual cookies. If the source handle did not read any cookies from a specific file on disk the cloned version of the handle would instead store the file name as `none` (using the four ASCII letters no quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from would then inadvertently load cookies from a file named `none` – if such a file exists and is readable in the current directory of the program usin
