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, thecookie-enable state is also cloned - but without cloning the actualcookies. If the source handle did not read any cookies from a specific file ondisk, 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 toload 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 theprogram using libcurl. And if using the correct file format of course.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2023-10-18T07:33:31.000000Z"}
