Summary
openssl on Windows built with openssldir set from the build machine (Uncontrolled Search Path Element)
Details

vcpkg is a free and open-source C/C++ package manager. Prior to version 3.6.1#3, vcpkg's Windows builds of OpenSSL set openssldir to a path on the build machine, making that path be attackable later on customer machines. This issue has been patched in version 3.6.1#3.
