05 Aug 2021 — libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users ... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-295: Improper Certificate Validation CWE-840: Business Logic Errors •
